Question
INDUCTORS Determine the equivalent inductance for two inductors in series and parallel. Determine the inductance of the toroid pictured below, assuming there are N turns. (a) If the switch in the circuit has been open for a long time, what is the current through resistor R1 immediately after the switch is closed? (b) If the switch in the circuit has been closed for a long time, what is the current through resistor R1 immediately after the switch is opened? If the initial charge on the capacitor is Q0 and the initial current through the circuit is zero, determine the charge on the capacitor plate and current through the inductor as a function of time. Determine the current through the system when the switch is in position a and position b.Explanation / Answer
1 a)The current, ( I ) that flows through the first inductor, has no other way to go but pass through the second inductor and the third and so on. Then, inductors in series have a Common Current flowing through them, for example:
IL1 = IL2 = IL3 = IAB
