"A certain capacitor, in series with a resistor, is being charged. At the end of 10ms its charge is half the final value. The time constant for the process is about: "
"A. 0.43ms B. 2.3ms C. 6.9ms D. 10ms E. 14ms"27/02/2013
"An initially uncharged capacitor C is connected in series with resistor R. This combination is then connected to a battery of emfV0.Sufficient time elapses so that a steady state is reached. Which of the following statements is NOT true? "
"A. The time constant is independent ofV0 B. Thefinal charge on C is independent ofR C. The total thermal energy generated by R is independent ofR D. The total thermal energy generated by R is independent ofV0 E. The initial current (just after the battery was connected) is independent ofC"27/02/2013
"A charged capacitor is being discharged through a resistor. At the end of one time constant the charge has been reduced by (1−1/e) = 63% of its initial value. At the end of two time constants the charge has been reduced by what pe RC ent of its initial value? "
"A. 82% B. 86% C. 100% D. Between 90% and 100% E. Need to know more data to answer the question"27/02/2013
"A. second/farad B. second/ohm C. 1/second D. second/watt E. none of these"27/02/2013
