Superposition theorem

Superposition theorem can be used to find the current or voltage in any circuit containing more than one independent sources. By using this method, we calculate the contribution of each independent source and sum them up. Superposition is not limited to circuit analysis but is applicable in many fields where cause and effect bear a … Read more

Current Division rule

As we know, in a parallel circuit current divides into all branches. The current flow through each branch is inversely proportional to the resistance offered by each one them. The branch having higher resistance allows lesser current and the branch having lesser resistance allows more current. Current division rule is applied while finding current flow … Read more

Difference between Higher potential and lower potential

Before getting into the topic, we have to keep two points in mind.1. Conventional Current flow. (The way Current is said to flow historically)2. ‎Actual current flow. (The way Current actually flows). By definition, current is the flow of charges, basically electrons. It is said to flow from a point of higher potential to lower … Read more

What is a short circuit?

A short circuit is a situation in which two or more different lines (having different voltage levels/ different phase/ different terminals) come in contact and finally leads to the flow of large short circuit currents that may damage the equipment or the system. In a three-phase system, a occurs when two or more phases come … Read more
