What are most modern 200 amp electrical meters marked with?

A) 200
B) 200 amps
C) 200 A
D) 200-A

Answer:

Most modern 200 amp electrical meters are marked with 'C) 200 A.'

Most modern 200 amp electrical meters are marked C) 200 A. The term amp is a unit of electric current named after Andre Ampere. Electrical meters, specifically ammeters, are used in series with the device whose current is to be measured because the electric current is the same for each component in a series circuit.

Understanding an ampere is essential in various applications as many electrical appliances, fuses, and circuit breakers are rated in amperes or amps. An ampere is defined as the amount of electric current that produces a specified force between two parallel wires carrying the electric current. Given the importance of ammeters for safely measuring currents in circuits, it is critical that they are clearly marked with their full-scale rating, whether it is 200 A or otherwise.
