Which of the following are the three primary electrical parameters?

The three primary electrical parameters are voltage, current, and resistance, which together form the fundamental concepts in understanding electrical circuits.

Voltage, measured in volts, represents the potential difference that drives electric charge through a circuit. It acts as the force that pushes electrons along the conductive path.

Current, measured in amperes, refers to the flow of electric charge. It indicates how much charge is moving through the circuit per unit of time and is essential in analyzing how much power is consumed by devices.

Resistance, measured in ohms, characterizes the opposition to the flow of current within a circuit. It is crucial for understanding how components in a circuit affect the overall functionality and behavior of the electrical system.

Together, these three parameters are encapsulated in Ohm's Law (V = I × R), which illustrates the relationship between voltage, current, and resistance. This law is fundamental in circuit analysis and design, making it necessary for any electrical apprentice to grasp these concepts thoroughly.
