Question

A circuit has a 2.6 V battery connected in series with a switch. When the switch is closed, the battery powers two paths in parallel, one of which has a resistor of resistance R1 = 90 ohm in series with an inductor of inductance L = 1.1 times 10-2 H, while the other has a resistor of resistance R2 = 280 ohm. What is the current supplied by the battery at a time t = 0.3 ms after the switch is closed? Which of the following circuit diagrams correctly represent the circuit described in this problem? Check all that apply. Consider the currents i1, i2. and i3 shown in the diagrams above. Using the junction rule at the appropriate junction, find an expression for i1, in terms of i2, and i3. Express you answer in terms of i2 and i3.
