ANSWER:

Problem 79

In figure 30-71, the battery is ideal and  = 10V,  = 5.0,  = 10, and L = 5.0 H. Switch S is closed at time t = 0. Just afterwards, what are (a) , (b) , (c) the current  through the switch, (d) the potential difference  across resistor 2, (e) the potential difference  across the inductor, and (f) the rate of change ? A long time later, what are (g) , (h) , (i) , (j) , (k) , and (l) ?

                                                                Step by Step Solution

Step 1 of 12

Given ,  , , and .

When switch  is closed, and no current flows through the inductor. After a long time,the currents have reached their equilibrium values and then the inductor acts as an ordinary wire.
