What is the current in the circuit

Reference no: EM131015680

A 7-V battery is connected across a 70-omegacap.gif resistor and a 288-mH inductor. What is the current in the circuit if the battery has been connected for a long time?

The switch is then set so that the battery is now disconnected. How much time does it take for the potential difference across the resistor in an LR circuit like that in Fig. to drop to 1.2 percent of its original value?
