Question:

a series LR circuit of a 2.0H inductor with negligible internal resistance, a 100 ohm resistor, a switch, and?

A series LR circuit of a 2.0H inductor with negligible internal resistance, a 100 ohm resistor, a switch, and a 9.0V power source. After the switch is closed, What is the maximum power delivered by the power supply?

Answer:

I imagine that the maximum power would be at the point where the inductor stops restricting the flow in which case it's just a typical resistive circuit: 9V divided by 100 R 0.01 amps 10mA. I may be wrong, it's been a while since I've done electronics.
P E?/R 9?/100 0.81 watts inductor is not a factor as after a small amount of time, it has no effect on the circuit. .
