Question
a) A 700 resistor is joined in series with a 700m Hinductance and a 18 Volts battery. What is the time constant of thecircuit? b) How long will it take after the circuit is completed forthe voltage across the resistor to reach 4.50 Volts? c) How long will it take after the circuit is completed forthe voltage across the resistor to reach 99 percent of 18Volts? ANY help would be greatly appreciated! a) A 700 resistor is joined in series with a 700m Hinductance and a 18 Volts battery.

ANY help would be greatly appreciated!Explanation / Answer
Resistance R = 700 ohm
Inductance L = 700 mH = 0.7 H
Maximum voltage V = 18 V
(a. time constant T = L / R
= 1* 10 ^ -3 s
