I need assistance on 2.1 and both parts of question 2.2
The basic geometric shape of inductors is the same as a solenoid (a coil of many loops). Such inductors are often used in a circuit through which a current I changes with time t, i e. I = I (t). Time-dependent current I (t) can produce a potential difference across an inductor V_L = -L Delta I/Delta t, where L is the inductance of the inductor. The inductance L...
