Kirchhoff’s laws, Wheatstone bridge

The Wheatstone Bridge is a basic circuit used for measuring unknown resistance in small amounts. The measurement of resistance is done by connecting the unknown value resistor with three resistors of known value in a quadrilateral arrangement. Then voltage is applied between one pair of opposite corners, and a galvanometer is connected to the other […]

Introduction The Wheatstone bridge was initially illustrated by Samuel Hunter Christie and was invented by Sir Charles Wheatstone. This bridge is designed to compare the electromagnetic forces in different metals. It measures the unknown resistance connected in electrical circuits. It has a diamond-shaped arrangement with four resistors, the so-called Diamond Method. Wheatstone Bridge The Wheatstone

It is essential to keep track of the minutest measurements of voltage, current and resistance in circuits because the slightest error, such as minute resistances in the wrong place, can lead to mistakes in calculations and physical applications of devices. This is where the Wheatstone Bridge comes in. The Wheatstone Bridge is a simple circuit

In electricity, a cell is a unit structure that generates an electrical current by some other mechanism other than a conductor moving in a magnetic field. The solar cell, for example, is made up of a semiconductor junction that enables sunlight to be converted into power. It is called a battery when we connect one

You might have seen Parallel and Series connections while researching lithium batteries.   But many don’t know how to differentiate between parallel and series connections. If you’re a novice to lithium batteries or batteries in general, this can be complicated, but hopefully, we can clarify. Let us start with the basics: your battery bank. When

When the branch constitutive relations of all circuit elements have an admittance representation, nodal analysis is possible. Nodal analysis generates a small set of network equations that can be solved by hand if the network is small or quickly solved by computer using linear algebra. The branch current method, also known as nodal analysis, node-voltage

The metre bridge contains a wire of length 1 metre of the uniform cross-section which is fixed between two metallic bands. So, it is known as the metre bridge. It is used to find an unknown resistance of a wire. Metre bridge wire is made of some alloy wires like Manganin or Constantan as the

The voltage loss across a circuit is dealt with by Kirchhoff’s second law. It asserts that if the voltage drop at each point of a circuit moves in either a clockwise or counterclockwise direction, the total voltage drop throughout the closed-loop must equal zero. This is the result of electric potential conservation. We’ll come back

Introduction In physics, it is mandatory to learn about laws of electricity such as Kirchhoff’s laws. These are  very important laws of electric physics. Using these laws, we can calculate the amount of total current or the value of current that flows in or out. Also, we can find the values of electronic components such

A capacitor is a component that, like a small rechargeable battery, can retain energy in the shape of an electrical charge that produces a potential difference across its plates. Capacitors come in various sizes and shapes, varying from tiny capacitor beads used in resonance circuits to enormous power converter capacitors. However, they all have a
