A capacitor is `5 mu F` is conneted to 20 V supply through a resistance R. What should be the value of resistance so that condenser acquires 63.2% of its final charge in 10 millisecond ? |

Answer» Here, `C = mu F = 5 xx 10^(-6) F, V = 20 v o l t, R = ?` To acqure 63.2% of its final charge, time required, `t = tau = RC = 10 xx 10^(-3) s` `R = (10 xx 10^(-3))/(C ) = (10^(-2))/(5 xx 10^(-6)) = 2 xx 10^(3) Omega` |
