Question

you take two resistors of the resistance 2R and 3R and connect them in parallel in an electric circuit. calculate the ratio of the electrical power consumed by 2R and 3R

Answer 1

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

Power = V²/R

Power of resistor with resistance 2R = V²/2R =P1

Power of resistor with resistance 3R = V²/3R =P2

P1:P2 = (1/2R) : (1/3R) = 3:2

please mark as brainiest=)

Answer 2

Answer:

Power = V²/R

Power of resistor with resistance 2R = V²/2R =P1

Power of resistor with resistance 3R = V²/3R =P2

P1:P2 = (1/2R) : (1/3R) = 3:2
