Transformer on load condition
A transformer is said to be on load when the primary is connected to the alternating voltage source and its secondary is connected to the load. When a transformer is…
Operation of Transformer on No load condition
A transformer is said to be at no load when the primary of a transformer is connected to the source of ac supply and the secondary is kept open. Similarly,…
What is an Ideal Transformer? Properties, Working, and Phasor diagram
An ideal transformer is a transformer that has no winding resistance(no copper loss), no core loss, no magnetic leakage, and zero magnetizing currents. But in existence, there is no such…
Save energy at home to create a sustainable future
Have you started to save energy at your home? Saving energy in every living place is the need of the hour to create a sustainable future. Saving energy will also…
AC resistance and impedance
AC resistance and DC resistance are the opposition offered to the flow of AC and DC currents respectively through a conductor. However, in AC circuits, the resistance is called impedance. Impedance…
Real power, Reactive power, and Apparent Power | Power Triangle
In an AC circuit, the total power consumed is called the apparent power. The power triangle is the representation of a right-angle triangle showing the relation between active power, reactive power, and apparent power. Almost…
Electrical Power in AC circuits
Electrical power is the rate at which the work is done or the rate at which the energy is being consumed in a circuit. Generally, all the electrical and electronic…
RL Series circuit
An RL series circuit consists of passive circuit elements such as an inductor and resistance connected together to a source. In an electrical circuit, an inductor opposes the rate of…
Inductors in Parallel
When inductors are connected in parallel, the voltage drop across each inductor would be the same. In the case of inductors in series, the equivalent inductance is obtained by adding…
