Current and potential difference in series and parallel circuits - questions

I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. Even if you don't want to study science or maths further, the grades you get now will open doors in the future.

I am currently doing triple science at school and I feel like the work load is too much. I think I would benefit from going in to duel award and my teacher says I can but I'm not sure if it is a good idea. Any ideas?

In the second last question won't A1 be 13.5A and A2 be 4.5A. On the line with A2 there are two bulbs meaning double the resistance. That results in half the current flowing down it and half of 9 is 4.5.

several mistakes in this video, pls look over

I got a circuit on my test and it was a parallel circuit, they did not give the voltage of the source but only one of the voltages of the bulb  (5V)  and they wanted to know the voltage of the source and the motor. I wrote 5V for those 2 but I got it wrong. Could u help me thanks...

Good video but I think you need to check your maths on a few questions
