Open Circuit: What is it? (And How Does it Differ To a Short Circuit)

What is an Open Circuit? An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a “closed circuit”. If there’s a break anywhere in the circuit, you have an open circuit, and current can not flow. In

Planar and Non-Planar Circuits: Analysis and Applications

A planar circuit is a circuit that can be drawn on a flat surface without any wires crossing each other. A non-planar circuit is a circuit that cannot be drawn on a flat surface without any wires crossing each other. Planar and non-planar circuits have different properties and methods of analysis. I

Three Phase Circuit | Star and Delta System

There are two types of system available in electric circuit , single phase and three phase system . In single phase circuit, there will be only one phase, i.e the current will flow through only one wire and there will be one return path called neutral line to complete the circuit. So in single phase

Relationship of Line and Phase Voltages and Currents in a Star Connected System

To derive the relations between line and phase currents and voltages of a star connected system , we have first to draw a balanced star connected system. Suppose due to load impedance the current lags the applied voltage in each phase of the system by an angle ϕ. As we have considered that the syste

Explain Diode and it’s Types

What is a Diode? Diodes are two-terminal electrical devices that act as a one-way switch, allowing current to flow (transfer) only in one direction. These diodes are made from semiconductor materials such as Silicon, Germanium, and Gallium arsenide. The diode’s two terminals are referred to as the A
