What is the primary current in unit of Ampheres Vac 220 Vrms 50 Hz RloadA series RL circuit has a 1 k ohm resistor and a 5 mH inductor. What is the time constant for the circuit?Instructions 50 cm 10 cm 8.0 A R = 1.0 × 10-3 N A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)
