As the number of batteries added in series increases, the brightness of the bulb increases.

# data[].attributes.body
As the amount of bulbs in series increases, the brightness of the bulb decreases. This is because more electric current is needed to flow trough each bulb.

# data[].attributes.body
As the number of batteries in series increased, the brightness of the bulb became stronger.

# data[].attributes.body
As the number of batteries arranged in series increase, the brightness of the bulb increases

# data[].attributes.body
The brightness of the bulb is the same.

# data[].attributes.body
As the number of batteries added in parallel increases the brightness of the bulb remains the same as the same amount of electric current flows through each bulb

# data[].attributes.body
As the number of bulbs increases, the brightness of the bulbs decreases.

# data[].attributes.body
as the number of bulbs in series increases, the brightness of each bulb decreases. as the number of bulbs in series increases, less electric current flows through each bulb.

# data[].attributes.body
When the number of batteries added in parallel increases, the brightness of the bulb remains the same.

# data[].attributes.body
The brightness of the bulbs are the same. The same electric current flows through the bulb.

# data[].attributes.body
As the number of batteries connected in parallel increases, the brightness of the bulb remains the same because the same amount of electrical current flows through the bulb.

# data[].attributes.body
As the number of batteries in parallel increases, the brightness of the bulb stays the same.

# data[].attributes.body
All the bulbs are of the same brightness even though there are more batteries in the circuit as only the battery nearest to the bulb has to conduct electricity to the light bulb, thus all the bulbs will receive the same amount of electricity even though there are more batteries in parallel in the circuit.

All the bulbs are of the same brightness even though the are more batteries in the circuit as only the battery nearest to the bulb has to conduct electricity to the bulb, thus all the bulbs will receive the same amount of electricity even though there are more batteries in the circuit.

# data[].attributes.body
As the number of bulbs added in parallel increases, the brightness of the bulbs remains the same as the same amount of electric current will be flowing through the bulbs. Therefore as the number of bulbs added in parallel increases the brightness of the bulbs does not change.

# data[].attributes.body
As the number of bulbs in parallel increases, the brightness of the bulbs remained the same as the amount of electricity flowing through the bulbs is the same.

# data[].attributes.body
As the number of bulbs added in series increases, the brightness of the bulbs decreases. This is because more electric current is needed to flow through each bulb, there is less electric current flowing through each bulb.

# data[].attributes.body
The brightness of the bulb increases when more batteries are added in series.
When more batteries are added in series, the more electric current flows through the bulb. Thus, the brightness of the bulb increases.

# data[].attributes.body
As the number of batteries arranged in series increases ,the brightness of the bulbs also increases.

# data[].attributes.body
As the number of batteries in series decreases, the brightness of the bulb decreases.

# data[].attributes.body
As the number of batteries in the circuit increases, the brighter the bulb becomes.
When there are more batteries, there is more electrical energy therefore, the bulb becomes brighter.

# data[].attributes.body
as the number of bulbs added in parallel increases, the brightness of the bulbs remains the same as the same amount of electric current flows through each light bulb.

# data[].attributes.body
The brightness of the bulb remains the same as when more batteries are added the same amount of electrical current flows through the bulb. Therefore, the brightness of the bulbs remain the same.

# data[].attributes.body
As the amount of bulbs in series increases, the brightness of the bulb decreases. This is because more electric current is needed for each bulb, hence electric current flowing through each bulb is lesser.

# data[].attributes.body
The brightness of the bulbs remains the same as the number of bulbs added in the circuit increases as the same amount of electric current flows through each bulb.

# data[].attributes.body
As the amount of bulbs increases,the brightness of each bulb decreases. As more electric current need to flow through each bulb.

# data[].attributes.body
As the number of bulbs connected in series increases, the brightness of the bulb decreases because there is less electric current flowing through each bulb

# data[].attributes.body
All the bulbs are of the same brightness even though there are multiple bulbs in the circuit.

# data[].attributes.body
Observations: As the number of bulbs placed in series increases, the brightness of each bulb decreases.
Reason: When more bulbs are added in series, the amount of electric current flowing through each bulb will be lesser as each bulb needs to have the same amount of volts.

# data[].attributes.body
As the number of bulbs added in series increase, the brightness of the bulbs decrease. There are lesser electric current passing through each bulb so the brightness of the bulb will decrease.

# data[].attributes.body
when the number of bulbs in parallel increases,the brightness of the bulb is the same

# data[].attributes.body
As the number of batteries in series increases,the brightness of the bulb increases.

# data[].attributes.body
The no. of batteries added affects the brightness of the bulb as there is more electrical energy therefore, there is the more the batteries, the brighter the bulb.

# data[].attributes.body
As the number of batteries placed in series in a circuit increases, the brightness of the light bulb increases.

# data[].attributes.body
The brightness of the bulbs remain the same when more batteries are added in parallel.
When more batteries are added in parallel, the same amount of electric current flows through the bulb. Thus, the brightness of the bulb remains unchanged.

# data[].attributes.body
When the number of bulbs added in series increases, the brightness of the bulb decreases.

# data[].attributes.body
When the number of bulbs added in a circuit increases, the brightness of the bulbs remain the same; equal.

# data[].attributes.body
As the number of batteries added increases, the brightness of the bulb increases.

# data[].attributes.body
When there were more bulbs, the electric current will be less flowing through each bulb. Thus, the bulbs will light up less.
