1 volt x 1 ampere is equal to:
Correct answer: C. 1 watt
- A. 1 coulomb
- B. 1 newton
- C. 1 watt
- D. 1 hp
Explanation
According to the formula for electrical power, Power (P) = Voltage (V) x Current (I). Hence, when you multiply 1 volt by 1 ampere, you get 1 watt. That's why option C is the correct answer. Option A (1 coulomb) is incorrect because coulombs measure electric charge, not power. Option B (1 newton) is also incorrect as newtons measure force and do not relate to electrical power. Lastly, Option D (1 hp) is incorrect because while it is a unit of power, it is much larger than 1 watt and does not represent the correct value derived from the given voltage and current.
