Alternating-Current Circuits
Direct current is a flow of electric charge in only one direction and has a steady state of constant voltage in the circuit. Rectifiers, batteries,…
The root mean square (RMS) value is a measure of the effective or average value of an alternating current (AC) waveform. In AC circuits, the voltage…
A capacitor is charged by passing an electric current through it, which causes the plates to start accumulating an electrostatic charge. Since the…
The basic components of an inductor are coils or loops of wire that are either wound around a hollow tube former or a ferromagnetic material…
When current flow is opposed in a DC or AC circuit, it is referred to as resistance or impedance, respectively. Impedance plays a key role in…
Consider an AC generator with a frequency of 50 hertz and a voltage of 120 volts. The AC generator is connected to an RLC series circuit with a…
The property of an inductor makes it resist any change in the current passing through it, while the property of a capacitor is to build up the charge…
A device that transforms voltages from one value to another using induction is called a transformer. A transformer consists of two separate coils, or…
Cardiovascular diseases are the leading cause of death in developed countries. Consequently, the demand for effective cardiac cell therapies has…
