As shown in the figure, a 1 Ω resistance is connected across a source that has a load line v + i = 100. The current through the resistance is

If the electrical circuit of figure (b) is an equivalent of the coupled tank system of figure (a), then

If the 12 Ω resistor draws a current of 1A as shown in the figure, the value of resistance R is

The switch in the circuit has been closed for a long time. It is opened at t = 0. At t = 0⁺, the current through the 1μF capacitor is
