Series and Parallel circuits

Current flow in a circuit is determined by the impedance offered by the circuit components, which is in turn determined by the way circuit components are connected. Series and parallel circuit connections are the two simplest ways of connecting a circuit. Series connection Series connected circuits consist of two or more active and/or passive devices … Read more

Difference between RCCB and RCBO

RCCBs and RCBO are residual current protection devices. Residual current protection is achieved by monitoring the flow of current in the line and neutral. In a healthy circuit, the current flow through the line will be equal to the return flow in the neutral. In the case of any abnormalities, this return flow may not … Read more

The direction of electric current

The direction of electric current can be a bit confusing topic. Here we have addressed your query. Hope this article shall be helpful to you in understanding the direction of current flow. Every particle in the nature other than the insulators* has a large number of free electrons in them. These electrons move randomly in … Read more

What is inductance?

  It is a property of a circuit element called inductor to store energy in the magnetic field when current passes through it. A basic inductor can be made by simply twisting a coil of a certain length. If current passes through an inductor, an electro magnetic field is formed.  Any change in the magnitude … Read more

What is voltage?

  There are two types of charges namely positive charge and negative charge. As we all know these charges are opposite and they attract . A work is done to separate these two charges through a specific distance. When these two charges are separated from each other certain amount of energy is stored in them in … Read more
