What is the current several seconds later

Reference no: EM13538019

An RL circuit has a V=7V battery, a R=15000Ohm resistor, and a L=0.7H, connected in series with a switch. The switch is left open for several seconds and then closed at time t = 0.

(a) What is the current at time t = 0?

(b) What is the current several seconds later? This is the maximum current.

(c) At what time was the current 95.0% of the maximum current?

(d) At what time was the current 63.2% of the maximum current?

(e) What percentage of the maximum current flows through the circuit at time t = 0.09333milliseconds?
