Mesh analysis or loop analysis involves the application of Kirchhoff’s voltage law to a circuit. KVL provides linear equations which are used to obtain current in branches. 5 Steps to Apply Mesh Analysis Assign a clockwise current direction to all loops in a network Label the loops and indicate the voltage polarity Apply Kirchhoff’s voltage … Read more
Basic Working Principle of Transformers made easy to understand for beginners.
Any type of electrical measurement device/equipment connected to a circuit impacts its electrical properties to some extent. A voltmeter connected to some high-value resistance can impact the actual resistance of the circuit, similarly, an ammeter connected in the circuit can impact the amount of current flowing in the circuit. The loading effect of electrical instruments … Read more
Inductors are simply added in series to obtain the equivalent inductance. Figure below illustrates this:
Inductors in parallel can be solved using the same formula as it is for resistors. i.e The overall inductance of the parallel circuit is:
