You take two resistors of resistance 2r and 3r
Asked by admin @ in Physics viewed by 288 People
You take two resistors of 2R and 3R connect them in parallel in an electric circuit.Calculate the ratio of electrical power clnsumed by 2R and3R.
Answered by admin @
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
