Basic Electrical Circuit

Let s start with three very basic concepts of electricity.

Basic electrical circuit. Electric circuits like ac lighting circuit battery charging circuit energy meter switch circuit air conditioning circuit thermocouple circuit dc lighting circuit multimeter circuit current transformer. Chapter 1 basic concepts of electricity pdf version. This current varying in parallel circuits brought about kirchoff s next big law in basic electrical engineering kirchoff s current law kcl. The battery provides required energy for flow of electrons to the light bulb.

As mentioned above in the introduction a circuit is an interconnection of elements. Electric charge refers to a fundamental property of matter that even physicists don t totally understand. Basic electrical circuits are made up three components voltage resistance and current. In a dc circuit current always flows one direction.

This article gives fundamental concepts about two types of electric circuits. Voltage e is an imbalance of electron distribution or a charge difference between two points measured in volts v resistance r is the opposition to current flow how hard it is for charges to move within the system the units of resistance are measured in ohms. Electric circuits are classified in several ways. Direct electric current and electricity.

Namely electric charge electric current and electric circuit. A simple electric circuit consists of a source such as a battery wires as conducting medium and a load such as a light bulb. In series circuits current is constant and voltage varies but in parallel circuits voltage is constant and current varies. The basic circuit thus helps a learner to gain understanding of the basic components and circuit s characteristics while it is in operation.

Ac and dc circuits. But what is electricity really. Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. An alternating current circuit carries current that pulsates back and forth many times each second as in most household circuits.

Depending on the type of source electricity varies as alternating current ac and direct current dc. Below is a very basic circuit consisting of a lamp a switch and a battery. Time for a little recap. The electrical energy coming from the battery is converted to heat and light energy by the light bulb.

Here are ten simple electric circuits commonly found around the home. For a more detailed discussion of direct and alternating current circuits see electricity. An electric circuit is a closed loop with a continuous flow of electric current from the power supply to the load. You might have been wondering how charges can continuously flow in a uniform direction through wires without the benefit of these hypothetical sources and destinations.
