Chapter 30, Problem 76E

(a)

To determine

To verify: The circuit equations are $R\left(i_1+i_2\right)+L\left(\frac{d{i}_1}{dt}\right)=\epsilon$ and $R\left(i_1+i_2\right)+\frac{q_2}{C}=\epsilon$.

(b)

To determine

The initial values of $i_1,i_2\text{ and }{q}_2$.

(c)

To determine

To show: By direct substitution that the given solutions satisfy the circuit equations and the initial conditions.

(d)

To determine

The time $t_1$ at which the current $i_2$ becomes zero.
