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.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
