1.	The expression for the current in an RC circuit is?(a) i=(V/R)e^t/RC(b) i=(V/R)e^-t/RC(c) i=(V/R)(1-e^-t/RC)(d) i=(V/R) (1-e^t/RC)This question was addressed to me in unit test.I want to ask this question from Transients in CR Networks topic in section Capacitance and Capacitors of Basic Electrical Engineering
Answer» Right CHOICE is (B) i=(V/R)e^-t/RC Easy explanation: APPLYING KVL to the GIVEN circuit, we get: i=i0e^-t/RC = (100/10)e^-t/100 i=10 e^-t/100.
