Question

If two resistors of resistance 30 $\Omega$ and 40 $\Omega$ are connected in parallel across a battery. The ratio of the potential difference across them is _____.

• A. $1:1$
• B. $2:1$
• C. $3:4$
• D. $4:3$

Answer 1

The correct option is A $1:1$

We know that in parallel combination of resistors, there is $same$ potential difference across each resistor as both are connected across same point in the circuit.

Hence ratio of potential difference is $1:1$.

Answer-(A)
