21) A series LR circuit consists of a battery, resistor, inductorand a switch. When the switch is closed the circuit has a timeconstant of 8.0 seconds. If the resistance and inductance of thecircuit are both doubled, what is the resulting timeconstant?
6) A 4.0 kW heater is designed to be connected to a 120 V rmssource. What is the power dissipated by the heater if it is insteadconnected to a 120 V DC source ?
