Question

You take two resistors of resistance 2 R and 3R and connected them in parallel in an electric circut. Calculate the ratio of the electric power consumed by 2R and 3R​

Answer 1

When resistors are connected in parallel, potential difference across them will be equal.

When resistors are connected in parallel, potential difference across them will be equal.Power = V²/R

When resistors are connected in parallel, potential difference across them will be equal.Power = V²/RPower of resistor with resistance 2R = V²/2R =P1

When resistors are connected in parallel, potential difference across them will be equal.Power = V²/RPower of resistor with resistance 2R = V²/2R =P1Power of resistor with resistance 3R = V²/3R =P2

When resistors are connected in parallel, potential difference across them will be equal.Power = V²/RPower of resistor with resistance 2R = V²/2R =P1Power of resistor with resistance 3R = V²/3R =P2P1:P2 = (1/2R) : (1/3R) = 3:2
