‘Cell and Battery are not the same things‘. How? We all use Batteries in our daily life. Mobiles, Laptops, wall clocks and some other devices need this to work. Do you know why we use a Battery? Yes, it is the source of electricity. In recent times, Electric cars gained popularity. These cars also use … Read more
Electricity is one of the most essential things in our daily life. To deal with an electrical circuit, we need to know the physical quantities associated with it. Current, Voltage, resistance, power, etc. are among those quantities. Many scientists have given various laws of electricity and explained how to determine such physical quantities in a … Read more
When an electric current flows through a resistor, a voltage drops across it. There is a simple way of measuring the voltage across a resistor by using a voltmeter. But, if we need to calculate it from the circuit parameters, then how can we do that? In this article, I’m going to explain the formula … Read more
Every device we use contains a circuit in it. A circuit consists of some circuit elements that are used for different purposes. These elements in a circuit can be connected in different ways depending on the functions for which these circuits are used. Based on the types of connections of the elements, electric circuits are … Read more
