yea , that's right. 1.5/0.12 = 12.5 ohm resistor. but the other one is 1.5/12 = 0.125 which is extremely low resistance for a bulb.niassu said:what was the choices for the 1.5v ? I've done it 0.12 A

i am sure,I made it wrong though, I though it was like a mug so made it 100cm^3. Ill explain shortly. The coffe cup is so small that it's diameter is something like 2cm, It's impossible to be 100cm^3 hence it's 10
and fo your question do u mean first question in the exam or the last page :O ? :Bravo: :Bravo: :Bravo: :Bravo: :Bravo:
