Difference between EMF and Voltage

The difference between EMF and voltage is that the EMF is the potential difference measured across a power source without a load connected to it whereas voltage is the potential difference measured between any two points in a circuit. We use the term EMF when we speak about batteries, generators, transformers, and other power sources … Read more

Difference between volts and amps | Volts vs amps

Volts and amps or ampere are two measures of electricity. Specifically, voltage is the measure of electric potential difference between two points whereas ampere is the measure of electric current. They are closely related terms and can be a bit difficult to understand. In this article, let’s learn the difference between volts and amps. What … Read more

Voltage and Electric potential difference

Voltage is the term used to refer to the potential difference. Every material in this world is made up of atoms. Each atom is made up of protons, electrons and neutrons, which are positively charged, negatively charged and electrically neutral respectively. As we know a force of attraction prevails between these positively charged protons and … 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
