Question

What must be the same for two resistors that are connected in parallel?


A. The resistance of each
B. The power used by each
C. The voltage drop across each
D. The current in each

Answer 1

in parallel combination : potential difference between two terminal of resistors are always constant.
in junction
Inet = i1 + i2 + i3 + ........
V/Req = V/R1 + V/R2 + V/R3 +......
1/Req = 1/R1 + 1/R2 + 1/R3 + .....

hence, potential difference ( voltage ) must be same across each resistor .

Answer 2

Correct option C.

When resistors are connected in parallel combination the voltage drop across each resistor is same. However , the total current gets branched into different amount .

But the total voltage supplied to the circuit remains constant across all resistors.
