    Physics paper 1 question

    A, because the wax melted and fell the most here. V=IR, 12= I*(10+20) , I=(12/30). V across the 10 ohm , V= (12/30) * 10 = 4V the total voltage is 12, so 12-4=8 which is the voltage across the 2o ohm resistor. This is a potential divider so it divides the voltage. I hope I helped.
