C+ -/2 points HRW10 27.P.066 My Notes C+ Ask Your Teacher The figure below shows two circuits with a charged capacitor that is to be discharged through a resistor when a switch is closed. In figure (a), R1 24.00 and capacitance C 6.40 HF. In figure (b), resistance R2 10.00 an capacitance C 8.00 HF. The ratio of the initial charges on the two capacitors is q02/q01 1.50. At time t 0, both switches in the two circuits are closed. At what time t do the two capacitors have the same charge? us Additional Materials Section 27.4 Submit Answer Save Progress Practice Another Version 5. -3 points HRW10 27.P.023 My Notes C+ Ask Your Teacher In the figure below, R 145 Q, R 200, and the ideal batteries have emfs E1 8.0 V, E2 5.5 v, E3 3.0 V

Explanation / Answer

the dischare equation is given by Q=qo*e^(-t/RC)

so,

q1*e^(-t/R1C1) = q2*e^(-t/R2C2)

or e^(-t/R1C1) = 1.5*e^(-t/R2C2)

or t*(1/R2C2 - 1/R1C1)=ln(1.5)

or t*(1/(10*8*10^-6) - 1/(24*6.4*10^-6))=ln(1.5)

or t=6.76*10^-5 s
