The335 kV AC electricity from a power transmission line is fed into the primary coil of a transformer. The ratio of the number of turns in the secondary to the number in the primary is. (a) What voltage is induced in the secondary? (b) What is unreasonable about this result? (c) Which assumption or premise is responsible?
Using RHR-1, show that the emfs in the sides of the generator loop in Figure \(23.23\) are in the same sense and thus add.
A cassette recorder uses a plug-in transformer to convert\(120{\rm{ }}V\)to\(12.0{\rm{ }}V\), with a maximum current output of\(200mA\).
(a) What is the current input?
(b) What is the power input?
(c) Is this amount of power reasonable for a small appliance?
An RLC series circuit has a \(2.50\;\Omega \) resistor, a \(100\;\mu H\) inductor, and an \(80.0\;\mu F\) capacitor. (a) Find the power factor at \(f = 120\;Hz\). (b) What is the phase angle at \(120\;Hz\)? (c) What is the average power at \(120\;Hz\)? (d) Find the average power at the circuit's resonant frequency.
Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time must the \(0.100{\rm{ }}A\) current through a \(2.00{\rm{ }}mH\) inductor be switched on or off to induce a \(500{\rm{ }}V\) emf?
