ITI Technician Interview Questions and Answers

1 ampere is the unit of electric current, representing the flow of one coulomb of charge per second.

• 1 ampere (A) = 1 coulomb/second (C/s)

• It is a fundamental unit in the International System of Units (SI).

• Example: A 1 A current flowing through a resistor produces a specific voltage drop.

• In household wiring, typical currents range from 5 A to 20 A for appliances.
