The circuit containing only a pure resistance of R ohms in the AC circuit is known asPure Resistive AC Circuit. The presence of inductance and capacitance does not exist in a purely resistive circuit. The alternating current and voltage both move forward as well as backwards in both the direct...
Interestingly, their individual resistances in ohms do not simply add. Because inductors and capacitors behave in opposite ways, they partially to totally cancel each other’s effect. Figure 1 shows anRLCseries circuit with an AC voltage source, the behavior of which is the subject of this secti...
mutual inductance M must be taken into account when analyzing circuit. even though they're separate loops, the Z_{eq} here think of them as one circuit. calculation is really messy. The lecture doesn't even tell you what mutual inductance is. That's strange.Pay attention to the minus sig...
such as voltage or current. In a pure AC capacitance circuit, the capacitor charges and discharges alternatively at the same frequency as the supply voltage. For capacitors, the current leads the voltage by90°.
The result is a mix of DC and AC at the signal load. The following schematic shows how an AC “noise” source may “couple” to a DC circuit through mutual inductance (Mstray) and capacitance (Cstray) along the length of the conductors. (Figure below) ...
An interesting variation on this theme is found in the next bridge circuit, used to precisely measure inductances. Maxwell-Wein Bridge Maxwell-Wein bridge measures an inductor in terms of a capacitor standard. This ingenious bridge circuit is known as theMaxwell-Wien bridge(sometimes known plainly...

The operation of circuit breakers causes switching surges that can result in interruption of inductive current, energization of lines with trapped charges, and single-phase ground fault. Modern circuit breakers, operating in two steps, reduce switching surges to 1.5–2 times the 60-Hz voltage.See...
