A) A 700 ohm resistor is joined in series with a 200 mH inductance and a 18 V battery. Determine what is the time constant of the circuit?
B) Find how long will it take after the circuit is completed for the voltage across the resistor to reach 9.00 V?
C) Find how long will it take after the circuit is completed for the voltage across the resistor to reach 99% of 18 V?
