Question

When r1 r2 r3 are connected in series then what will be the resultant resistant R of the combination

Answer 1

Answer:

Here the supply potential is VAB between the points A and B. Since the resistors R1, R2 and R3 are connected in parallel combination the potential difference across each resistor is same as the supply. Hence VAB = VR1 = VR2 = VR3. VR1 is the potential across the resistor R1
