1. Comment so as to do ONE of the following:

·enhance your friends’ anwers/presentation

·offer alternative working/presentation

·raise question(s) to clarify doubts about your friends’ answers/presentation.

2. Answers (s.f., units, etc…)

·Presentation /working

·Approach to solve the problem

3. Examples of comments

I like the way XXX presented his working.  XXX presented his working such that it is easy to follow his train of thoughts.

The resistance of the resistor in the center of the circuit is wrong. It is supposed to be 6 ohms not 10 ohms.

# data[].attributes.body
Isn’t the ans for part c 2A,you should find the voltage of 4ohm resistor ,then subtract it from the emf of the circuit to find the voltage flowing through the parallel circuit consisting of 3 and 6 ohm resistor which is the same since they are a parallel circuit.Then you would be able to use the formula,R=V/I to find current flowing through 3 ohm resistor

# data[].attributes.body
Should do the 1/ re first before calculating the total as it will seem very weird in the workings to have 1/1/6 and it will be a better presentation

# data[].attributes.body
Workings are presented clearly as there are labelings for each step. Very
Systematic and clear

# data[].attributes.body
I suggest writing workings for the questions

# data[].attributes.body
Should be 1/Re instead of just 1/R

# data[].attributes.body
Working is very clear and understandable.

# data[].attributes.body
Workings are very straightforward and clear.

# data[].attributes.body
The working and the presentation of the working is clear and easy to understand.

# data[].attributes.body
current flowing through the 4ohm resistor is the total current flowing in the circuit hence you should use emf of the source divided by the total effective resistance in the circuit

# data[].attributes.body
yo please include your working thank

# data[].attributes.body
The circuit is correct but there are no workings

# data[].attributes.body
the circuit diagram is correct and the workings are understandable

# data[].attributes.body
Should connect the ammeter to a component or the wire to show current

# data[].attributes.body
Should write the formula to make workings clearer

# data[].attributes.body
The simplified drawing on the right makes the question clearer

# data[].attributes.body
One of your drawings is wrong as the 4.0 ohm resistor is in series not parallel

# data[].attributes.body
I think 0.5A should be obtained by subtracting the voltage provided by 2ohms resistor from emf of cell 5V, then then use I= V/R of resistor 2ohms.

# data[].attributes.body
Why is ur phet stimulation shape so abstract and different from the question

# data[].attributes.body
You should show the formula u are using to solve

# data[].attributes.body
i think your workings can be improved ; include the equation such as R=V/I for more clearer working but other than that it is okay

# data[].attributes.body
the one on the right is the working

# data[].attributes.body
The answer for part c can be presented clearer, it’s hard to tell if the answer is 6A or 2A

# data[].attributes.body
If im not wrong, effective resistance refers to the overall resistance. The resistance we initially calculated for part (a) is not the overall resistance we’re calculated. Thus, we did not use 1/effective resistance

# data[].attributes.body
Part d should either not have unit in working or have unit in the whole working

# data[].attributes.body
Good presentation for part A. Very detailed, easy to understand.

# data[].attributes.body
Clear and easy to understand

# data[].attributes.body
The working is clean and understandable

# data[].attributes.body
Should show the workings for part A.
Workings for part c is a bit messy.

# data[].attributes.body
Formula should be included before finding the answers.

# data[].attributes.body
I suggest writing the statements eg effective resistance=...) before trying to find the answer
