Ampere-second is the unit of

Ampere-second is the unit of:

1. Charge
2. Energy
3. Power
4. EMF

Correct answer: 1. Charge

Explanation: Ampere-second (A·s) is the unit of electric charge.

• The ampere (A) is the unit of electric current, and when multiplied by time (in seconds), it gives the quantity of electric charge that has passed through a conductor.
• The formula for electric charge (Q) is given by Q = I * t, where Q is the charge in coulombs (C), I is the current in amperes (A), and t is the time in seconds (s).
• Therefore, when you multiply the current in amperes by the time in seconds, you get the charge in coulombs, and the unit of charge is the ampere-second (A·s).
