Introduction What is an electrical circuit? An electrical circuit is a path or line through which an electrical current flows. The path may be closed (joined at both ends), making it a loop. A closed circuit makes electrical current flow possible. It may also be an open circuit where the electron flow is cut short because the path is broken. An open circuit does not allow electrical current to flow.

Below is a basic set of symbols that you may find on circuit diagrams.

It is very important to know the basic parts of a simple circuit and the symbols that relate to them. A simple circuit has conductors, a switch, a load and a power source. Here are the functions of each part: Conductors: These are usually copper wires with no insulation. They make the path through which the electricity flows. One piece of the wire connects the current from the power source (cell) to the load. The other piece connects the load back to the power source. Switch: The switch is simply a small gap in the conductor where you can close or open the circuit. When the switch is closed, the circuit is closed and electricity flows. The Load: The load is a small light bulb or buzzer that lights when the circuit is turned on. The load is also known as a resistor. Cell: The power source is a cell. (Note that more than one cell put together is known as a battery)

The diagram below shows how a basic circuit looks like : - .

There are two types of circuits namely Series Circuit and Parallel Circuit.

Circuit Analysis 1. From both circuit, we can analyze to measure or calculate the voltage, current, energy and power. 2. By using different technique or formulae or Law/Rules such as Ohm’s Law. 3. So that, you have to familiar with the mathematical and units. 4. The calculation may involve real and complex number

Conclusion • So in this subject , you will do some analysis – to calculate voltage, current, power and energy with the help of formula and by using different techniques. • From easy to uneasy .

• Make sure student know and familiar with Scientific Calculator. • Notes will be upload @ student portal. Lecturer Notes >> Jabatan Teknologi Kejuruteraan Elektronik >> SUBJEk YANG DIAMBIL OLEH SEMUA RY >> SEM 1 2018/2019 >> PGT 101 ELECTRIC CIRCUIT THEORY
