$7.$ The oscillogram shown in Figure Q$7($a$)$ was obtained while analyzing the circuit in Figure Q$7($b$).$ Th eoscilloscope controls were adjusted as follows:

$\frac{V}{d}iv(Y_A)=2V$

$\frac{V}{d}iv(Y_B)=$ unknown

Time $\frac{?}{?}$ div $=5ms$

$($a$),Y_A$ represents the voltage $v_L(t)$ and

$($c$),Y_A$ represents the voltage $v_{LC}(t)Y_B$ represents the voltage $v_{RL}(t)$ and $Y_B$ represents the voltage $v_C(t).$

$($b$),Y_A$ represents the voltage $v_R(t)$ and

$($d$)Y_A$ represents the voltage
