Electric current: Ohm’s law, resistivity

A machine that converts electrical energy into mechanical energy is known as an electric motor. When a current-carrying conductor is put in a magnetic field, it is subjected to forces that aid in shaft or axle rotation. A motor is a mechanical device that converts electrical energy into mechanical energy. Spinning blades in a mixer, […]

Electrical generators are self-contained units that generate power when the local grid is unavailable. During power outages, these generators provide backup power to businesses and homes. Generators do not produce electrical energy; instead, they convert mechanical or chemical energy into it. Generators are divided into two types based on their output: AC generators and DC

Current  Current is defined as the flow of electrically charged particles, which occurs mostly in electron-deficient atoms. The capital I is the conventional symbol for current. Ampere ( A ) is the standard unit of current. A current of one ampere, on the other hand, is one coulomb of charge passing through a specific place

Introduction There are two ways to measure electricity: current with an ammeter and voltage with a voltmeter. These devices are employed in electric circuits; however, the ammeter is more useful for measuring current flow. The voltmeter is more useful for measuring voltage or emf across two points in an electric circuit. What is the Difference

A single charged particle doesn’t have to go from the source of the current (the current source) to the consumers of the current. To power your device, all the particle has to do is nudge its neighbour a finite amount, who will then nudge their neighbour, and so on, until a particle gets nudged into

The object that will get charged or not, it totally depends on what kind of material is used in making the object? Either the material used is conductive or non-conductive in nature. Because the material which is conductive in nature will allow the heat and electricity to pass through it and we call it as

The electromotive force (EMF) and the voltage or potential difference (PD) between the terminals of a battery at a location in an electrical or electronic circuit can be easily confused. Although EMF and possible differences measure volts, the two metrics are quite different.  The electromotive force is caused by converting another form of energy into

When the current flows through the electrolyte present in an electrolytic cell, the solution offers internal resistance to the flow of current across it. When the current doesn’t flow through the circuit, then the potential difference in such a condition is termed electromotive force. Emf of a cell An electric cell has potential due to

Introduction A current is slowed by resistance, which is an electric property. A current flowing through a wire (or resistor) is analogous to water running through a pipe, and the voltage drop across the wire is analogous to the pressure drop that forces the water through the pipe. Conductance is proportional to how much flow

An electric circuit is the path of the flow of electric current. Different components of an electric circuit are capacitors, resistors, wires, switches, and batteries. Circuit theory defines the techniques that describe this flow. The principle of circuit theory depends upon different laws and ideas, such as Kirchhoff’s law and Ohm’s law. These laws help
