An R–L circuit with a DC battery and a switch S, is as shown:The switch is closed at t=0. The ratio of maximum to minimum power delivered by the battery is mn, where m and n are coprime integers. Find m+n.

Bryson and Diego decide to work a practice problem.A resistor, inductor, and a battery are arranged in a circuit. The circuit has an inductance of L = 2 H, and a resistance of 2 kΩ. Switch S1 is suddenly closed at t = 0. Find the time needed for the current to reach a fraction f = 0.5 of its maximum value.

For the circuit in the given figure,

Ishani and John now try a problem involving a charging capacitor.An uncharged capacitor with C = 3.62 𝜇F and a resistor with R = 9.0 105 Ω are connected in series to a 12.0 V battery. The switch is closed at time t = 0, allowing the capacitor to charge.Find the maximum charge on the capacitor and the maximum current through the resistor.

Two resistors 2 and 4 are combined in parallel. If this combination isconnected to a battery of 16 𝑉, the maximum current that can be drawn fromthe battery is __________ 𝐴 (rounded off to the nearest integer

n the circuit shown below, the voltage across the battery terminals is measured to be 12 V when the switch, S, is open. When S is closed, this voltage falls to 8 V and the resistor, R, is then dissipating a power of 100 W. The internal resistance of the battery in Ohms to two decimal places is:
