Question

The ratio of the resistances of two resistors connected in parallel is 2:3. The ratio of the currents flowing through them, when this parallel combination is connected to a cell is

• A. 3:2
• B. 2:3
• C. 1:1
• D. 5:3

Answer 1

The correct option is A 3:2

$R_1:R_2=2:3$

$I=\frac{V}{R}$

We know that in parallel combination of resistors, potential difference across each resistor is same.

$⟹I\propto \frac{1}{R}$

Hence, $\frac{I_1}{I_2}=\frac{R_2}{R_1}=\frac{3}{2}$

$⟹I_1:I_2=3:2$

Answer-(A)
