AC Circuit Containing Resistance, Inductance and Capacitance Circuit (LCR in series) - When an AC source is connected in a circuit with a resistance and a reactance together, the current varies initially in a complex way. After sufficient ..

When an AC source is connected in a circuit with a resistance and a reactance together, the current varies initially in a complex way. After sufficient time, a sinusoidally varying current persists in the circuit. This steady state current has a frequency equ..

AC Circuit with Pure Capacitance only - Let an AC source be connected across pure inductive element. If E = E o sin w t then, q = EC = CE o sin w t I = I o cos w t Here I o = E o C w = E o C w plays the role of a resistance and is known as capacitive reactance X c..

Let an AC source of EMF E be connected to a pure resistance R. The instantaneous EMF from the source is given by E = E o sin w t From Ohm's law I = E/R = E o /R . sin w t I = I o sin w t The variation of E and I shows that both reach maximum and zero value at the same instant..

Let an AC source be connected across a pure inductive element. If the alternating current I = I o sin w t flows through it. Then According to Kirchhoff's Law E = E o cos w t or..

Arithmetic operations such as addition, subtraction and complex operations such as multiplication, division etc., are performed by using digital circuits called adders, which again consists of basic logical gate..

Arithmetic operations such as addition, subtraction and complex operations such as multiplication, division etc., are performed by using digital circuits called adders, which again consists of basic logical gates. Repeated addition gives multiplication. Repeated subtraction give..

In many electrical circuits, Ohm's law cannot be applied. This happens when there is more than one source of emf in the circuit or when resistors are connected in a complicated manner. To solve such complex circuits, Gustav Robert Kirchhoff developed tw..

Logic Gates - The basic building blocks for a complex digital system are known as logic gates. A gate is a simple electronic circuit or device that performs logical functions. It has one or more inputs and one output gate and are also called binary logic gates, as 1 and 0 are th..
