Questions
A capacitor, initially charged to 5V, is started charging at t=0 by a source at the rate of . How long will it take to raise its potential to 10V?
detailed solution
Correct option is A
q=CV dqdt=CdVdt 40 t x 10-6=CdVdt 40 t x 10-6dt=16 x10-6dV on integrating 40t22=16(10-5)=80 t=2sTalk to our academic expert!
