1.0 A multiloop circuit. Wht are the currents in the three branches? Whas is the potential difference between points a and bi Ri 6.-2.1 V, R.-1.7, 6,-6.3 V R2-3.5 . (b) Calculate the power delivered to each resistor in the circuit

Solution

a) the formula for RC circuit and charge in capacitor is

q = q_o (1-e^{t/RC )}

for 50% charge

Put q= q_o /2 , and we will get

=>1/2 = 1 - e^-t/RC

^=>e^-t/RC = 1/2

^=> -t/ RC = ln 1/2

=> t = RC ln 2

b) For complete charge

Put q = qo , and we will get

=> 1 = 1 - e^-t/RC

So in reality the capacitor never becomes 100% charges as t is edging to infinity here in this equation.
