What are the 3 basics of electricity?
There are three primary electrical parameters: the volt, the ampere and the ohm.
- The Volt. The pressure that is put on free electrons that causes them to flow is known as electromotive force (EMF). …
- The Ampere. The ampere defines the flow rate of electric current. …
- The Ohm. The ohm is the unit of resistance in a conductor.

What are types of electricity?
There are two main types of electricity, Static Electricity, generated by rubbing two or more objects causing to build up friction, Current Electricity, generated by the flow of electrical charge through a conductor across an electrical field.
What is current and voltage?
Definition. Voltage, also called electromotive force is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points. Current is just the rate of flow of electric charge.
What is current unit?
Unit of electric current: ampere (A)
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.
What is current formula?
Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.
What are the two types of voltage?
Two Common Types of Voltage: Direct and Alternating Current
There are two common ways of transferring electrical energy: direct current and alternating current.

What is the basic of electrical engineering?
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism.
What is AC current and DC current?
Electric current flows in two ways as an alternating current (AC) or direct current (DC). In alternating current, the current keeps switching directions periodically – forward and backward. While in the direct current it flows in a single direction steadily.
What is the law of electricity?
The most fundamental law in electricity is Ohm’s law or V=IR. The V is for voltage, which means the potential difference between two charges. In other words, it is a measurement of the work required to move a unit charge between two points.
Why is a circuit called a circuit?
In an electronic circuit, electrons come out of the power source, travel along conductors, go through a load to perform work and are finally returned to the source. It is called a circuit because of the circular path that the electrons flow through.
What is electric fuse?
An electrical fuse is a safety device that operates to provide protection against the overflow of current in an electrical circuit. An important component of an electrical fuse is a metal wire or strip that melts when excess current flows through it.
What is the symbol for a bulb?
A light bulb is shown as a circle with a cross inside it.
What is node and Junction?
A point at which two or more elements are joints together is called node. While a point where three or more branches meet together is called a junction. In the below figure we can say that points a,b,c,d,e and f are nodes and point c & f are called junction.
What is loop in circuit?
Loop – A loop is any closed path going through circuit elements. To draw a loop, select any node as a starting point and draw a path through elements and nodes until the path comes back to the node where you started.
What is mesh or loop?
A loop is any closed path through a circuit where no node more than once is encountered. A mesh is a closed path in a circuit with no other paths inside it. To find a loop, start at a node in the circuit, from this node, move back to the same node along a path to ensure that no node is encountered more than once.
