Question

A resistor R and another resistor 2R are connected in series across a battery. If heat is produced at a rate of 10 w in R, then in 2R it is produced at a rate of 40 W 20 W 10 W 5 W What is the value of the charge on a cap at time t = t_Rc when the capacitor is charging assuming the initial charge of the capacitor is zero coulombs 37% of Q_max 63% of Q_max 50% of Q_max 75% of Q_max Capacitance is a purely ___________ quantity. Magnetic Electric Quantized Geometric What is the criteria under which Angular Momentum is Conserved?

Explanation / Answer

2) P = I^2 *R

I remains same when the resistors are in series

I = sqrt(10/R)

P1 = I^2 * 2R

=10/R *2R

= 20 W

option b is correct
