Thanks for the reply.
"If I measure the current at point A will it 0.02 A? I mean at A it has not passed through the resistance. So shouldn’t it be greater than 0.02 A and when meeting the resistance it reduces to 0.02A?"
I still have doubts about it. I am posting the same question in a...
Consider the circuit in the attachment
I know that the current is the same in a series circuit and voltage is divided at the 3 resistors. And resistance is added.
R = R1 + R2 + R3 = 100 + 200 + 300 = 600 Ω.
V = IR, 12 = I * 600, I = 0.02 amps = current flowing through the circuit.
V1...
