You take two resistors of 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?
Two resistance of value, =2Rand3R When resistors are connected in parallel, the potential difference across them will be equal. Step 2, Finding the ratio We know, Power =V2R Power of resistor with resistance 2R, =V22R=P1 Power of resistor with resistance 3R,=V23R=P2 Taking ratio of both power, P1P2=V22RV23R=3R2R=32 Hence, ratio of electric power consumed by 2 R and 3R, =3:2
