Basic Concepts of Electricity
The basic concepts of electricity are charge, current, voltage, and resistance. Charge is a fundamental property of matter that can be either positive or negative. Current is the flow of charge through a conductor. Voltage is the difference in electrical potential between two points.
Resistance is the opposition to the flow of current through a conductor.
The relationship between these four quantities is given by Ohm’s law, which states that the current through a conductor is directly proportional to the voltage across the conductor and inversely proportional to the resistance of the conductor.
Types of Electrical Circuits
- Series circuits
- Parallel circuits
- Combination circuits
Series circuits are circuits in which the components are connected in a single loop. Parallel circuits are circuits in which the components are connected in multiple loops. Combination circuits are circuits that contain both series and parallel connections.
