Electrical Engineering MCQ Questions with answers on Electrical Engineering Units and quantities.

Voltage, Current, Power, Resistance, Energy, Conductance, and Inductance are some of the basic electrical engineering quantities. Voltage is measured in volts, current is measured in amps, power is measured in watts, and resistance is measured in ohms. As a beginner in starting your Electrical Engineering degree, understanding the basic electrical engineering units and quantities is quite important. Even if you are already a pro, let’s revise your basic knowledge. Given below are MCQ-based questions on Electrical Engineering units and quantities.

SI Unit of Resistance is

SI unit of Resistance is:

1. volts
2. amps
3. ohms
4. watts

Explanation: The correct answer for this Electrical Engineering MCQ is ohms.

Resistance is a measure of how much a material or component opposes the flow of electric current. It is represented by the symbol “R” and is measured in ohms (Ω). The unit “ohm” is named after the German physicist Georg Simon Ohm, who formulated Ohm’s Law, which describes the relationship between voltage, current, and resistance in an electrical circuit.

SI unit of Power is

SI unit of Power is:

1. volts
2. amps
3. ohms
4. watts

Explanation: The correct answer is watts.

Power is the rate at which work is done or energy is transferred or transformed. It is a fundamental concept in physics and engineering. The SI unit of power is the watt (W), named after James Watt, the Scottish engineer who made significant contributions to the development of the steam engine. Continue Reading

SI unit of voltage is

SI unit of voltage is:

1. volts
2. amps
3. ohms
4. watts

Explanation: The correct answer is “volts.”

Voltage is a physical quantity that measures the electric potential difference between two points in an electric circuit. It is denoted by the symbol “V” and is named after the Italian physicist Alessandro Volta. The SI unit of voltage is the “volt” (V), which is defined as the potential difference across a conductor when a current of one ampere flows through it and produces a power dissipation of one watt.
