What is used to measure the strength of electricity?

Amps
Ohms
Volts
Watts

The correct answer is: Amps

Electrical strength does not refer to one specific measurement, but rather the degree or intensity of electrical current. Amps, or amperes, are the unit of measurement used for electrical current and are therefore the most accurate choice. Ohms measure resistance, volts measure electrical potential, and watts measure power, so these options are not appropriate for measuring the strength of electricity.
