Generally, power is the capacity to do work. In the electrical domain, electric power is the amount of energy transferred to some other form per unit of time like light, heat, etc. Mathematically, it can be defined as the product of voltage and current. Consider the DC circuits, which have only one voltage source either a voltage source or a current source, so the capacitors work as an open circuit within a steady-state whereas the inductors work like a … [Read more...]
What is a Power Supply : Types for Electrical Circuits
The power supply is the essential component in every electrical or electronic system. There are various requirements that need to be considered while choosing an exact power supply such as; necessities of power for the circuit or load mainly include voltage and current. The safety features of the power supply circuit like current and voltage limits for protecting the load, efficiency, physical size, and system noise immunity. In this article, we look into … [Read more...]
