# data[].attributes.body
-Electrical power is the rate of using electrical energy
-measured in joules/second (J/s) ( JS-1 )

# data[].attributes.body
-The greater the resistance in a circuit, the smaller the current flows

-The greater the p.d. in a circuit, the greater the current that flows

Difference of Electromotive Force and Voltage

# data[].attributes.body
- Emf is the voltage generated by a supply of energy (battery/cell/generator)
-Voltage can be measured between any 2 points, but Emf exists only between 2 ends of a source
-Voltages in a circuit called 'Voltage Drops' are in the opposite direction of Emf, their sum is equal to Emf according to Krichhoff's 2nd law.

# data[].attributes.body
-The Voltmeter is connected across the relevant components and to measure the voltage

-Ammeters are connected in series, to measure the current

-Battery/Cell is the supply of energy

-Resistor is used to maintain a large current to prevent the circuit from breaking/the bulb exploding
-unit is ohm

# data[].attributes.body
-The rate of flow of charge
-a flow of electric charge from 1 point to another
-SI Unit of current = Coulomb/Seconds (C/s) OR Amperes (A)

# data[].attributes.body
-Electromotive force (emf) is a difference in potential that tends to give rise to an electric current
-The cell supplies energy but not charges. Its function is to drive the free electrons in the circuit to flow
-unit of emf is JC-1 or volt, V
-1 V = 1JC-1

# data[].attributes.body
-current direction is always from positive to negative

-While electrons flow from negative to positive

# data[].attributes.body
-Potential Difference (p.d.) is also called voltage
-measured by voltmeter
-unit is volt (V)
-Voltmeter is connected parallel across the component
