SI unit of current is:
- volts
- amps
- ohms
- watts
Correct answer: 2. amps
The correct answer to the multiple-choice question is 2. amps, which stands for amperes. The SI unit of current is amperes, symbolized by the letter ‘A’.
Current refers to the flow of electric charge in a circuit or conductor. It is the rate at which electric charge moves through a given cross-sectional area of a conductor. The ampere is named after the French physicist André-Marie Ampère, who made significant contributions to the field of electromagnetism.
Volts (1) are the SI unit of electric potential difference, also known as voltage. Ohms (3) represent the SI unit of electrical resistance, named after the German physicist Georg Simon Ohm. Watts (4) are the SI unit of power, which is the rate at which work is done or energy is transferred.
Therefore, the correct SI unit for current is amperes (amps).
