Electrical systems operate based on fundamental parameters that define how electricity flows and interacts with various components. The key electrical parameters include voltage, current, resistance, and power. Let's explore each of these in detail. ELECTRICAL PARAMETERS: a) Electrical Voltage Voltage is the electrical force that moves electrons through a conductor. It is also called Electro Motive Force (EMF) as it pushes electrons within a circuit. The unit of voltage is volts (V). Example: A 230V power supply provides the force needed to operate household electrical appliances. b) Electric Current Electric current is the flow rate of electrons through a conductor. It is measured in Amperes (A). Example: When you switch on a fan, an electric current flows through the circuit, powering the motor inside. c) Resistance Resistance is ...
