# Question: A 10 mH inductor has a sudden current change

A 10-mH inductor has a sudden current change from 200mA to 100mA in 1ms. Find the induced voltage.

**View Solution:**## Answer to relevant Questions

The induced voltage across a 10-mH inductor is v (t)=120cos(377t) V. Find (a) the expression for the inductor current and (b) the expression for the power.The current in a 10-mH inductor is shown in Figure P5.28. Find the voltage across the inductor. Find the possible capacitance range of the following capacitors. a) 0.068 F with a tolerance of 10% b) 120pF with a tolerance of 20% c) 39F with a tolerance of 20%The two capacitors in Figure P5.42 were charged and then connected as shown. Determine the equivalent capacitance, the initial voltage at the terminals, and the total energy stored in the network. Compute the equivalent capacitance of the network in Figure P5.52 if all the capacitors are 5µF.Post your question
