Q5. What is frequency
Ans. 
Frequency refers to the number of occurrences of a repeating event per unit of time.
• Frequency is measured in Hertz (Hz), where 1 Hz is equal to 1 cycle per second.

• Higher frequency means more cycles per second, while lower frequency means fewer cycles per second.

• In electronics, frequency is used to describe the rate at which alternating current changes direction.

• For example, a frequency of 60 Hz means the current change
