Current Division Rule A parallel circuit acts as a current divider as the current divides in all the branches in a parallel circuit, and the voltage remains the same across them. The current division rule determines the current across the circuit impedance. The current division is explained with the help of the circuit shown below: …
Capacitance is defined as the capability of an element to store electric charge. A capacitor store electric energy in the form of the electric field by the two electrodes of a capacitor, one as positive and other as negative. In other words, capacitance is a measure of charge per unit voltage that can be stored …
The Inductance is the property of a material by virtue of which it opposes any change of magnitude and direction of electric current passing through the conductor. In other words, it is the property of the coil in which the emf is induced because of the variation of flux. The inductance is added in the …
The resonant frequency condition arises in the series circuit when the inductive reactance is equal to the capacitive reactance. If the supply frequency is changed the value of XL = 2πfL and XC = 1/2πfC is also changed. When the frequency increases, the value of XL increases, whereas the value of XC decreases. Similarly, when …
Resistance is the property of a material by virtue of which it opposes the flow of electrons through the material. It restricts the flow of the electron through the material. It is denoted by (R) and is measured in ohms (Ω). When the voltage is applied across the resistor the free electrons start accelerating. These …
In the RLC series circuit, when the circuit current is in phase with the applied voltage, the circuit is said to be in Series Resonance. The resonance condition arises in the series RLC circuit when the inductive reactance is equal to the capacitive reactance. XL = XC or (XL – XC = 0) A series …
When a pure resistance of R ohms, a pure inductance of L Henry and a pure capacitance of C farads are connected together in series combination with each other then RLC Series Circuit is formed. As all the three elements are connected in series so, the current flowing through each element of the circuit will …
A circuit that contains pure resistance R ohms connected in series with a pure capacitor of capacitance C farads is known as RC Series Circuit. A sinusoidal voltage is applied and current I flows through the resistance (R) and the capacitance (C) of the circuit. The RC Series circuit is shown in the figure below: …
A circuit that contains a pure resistance R ohms connected in series with a coil having a pure inductance of L (Henry) is known as RL Series Circuit. When an AC supply voltage V is applied, the current, I flows in the circuit. So, IR and IL will be the current flowing in the resistor …
The circuit containing only a pure capacitor of capacitance C farads is known as a Pure Capacitor Circuit. The capacitors stores electrical power in the electric field, their effect is known as the capacitance. It is also called the condenser. The capacitor consists of two conductive plates which are separated by the dielectric medium. The …
