Which of the following quantities has SI unit as Hertz

Electrical Engineering XYZ MCQ

Which of the following quantities has SI unit as Hertz:

1. Frequency
2. Charge
3. Power
4. Force

Correct answer: 1. Frequency

Explanation: Frequency is the SI unit of hertz.

1. Frequency:
   • SI Unit: Hertz (Hz)
   • Definition: Frequency is the number of cycles or oscillations of a wave per unit of time. The unit Hertz (Hz) represents one cycle per second.
2. Charge:
   • SI Unit: Coulomb (C)
   • Definition: Charge is a measure of the electric charge of a particle or object. The unit Coulomb represents the amount of electric charge transported by a current of one ampere in one second.
3. Power:
   • SI Unit: Watt (W)
   • Definition: Power is the rate at which work is done or energy is transferred or converted. The unit Watt represents one joule of energy per second.
4. Force:
   • SI Unit: Newton (N)
   • Definition: Force is the interaction that, when unopposed, will change the motion of an object. The unit Newton represents the force required to accelerate a one-kilogram mass at a rate of one meter per second squared.

In summary, the SI unit Hertz is associated with the quantity of frequency, which measures the number of cycles per unit of time.
