The domestic electricity supply has a frequency of:
Correct answer: C. 50 Hz
- A. 150 Hz
- B. 100 Hz
- C. 50 Hz
- D. 25 Hz
Explanation
The standard frequency for domestic electricity supply varies around the world, but it is commonly 50 Hertz (Hz). The specific frequency depends on the region and the standards established by the local electrical grid.It's important to note that the frequency of the electricity supply is a key parameter in electrical systems and devices, and appliances are designed to operate at the frequency of the local power grid.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
