Question

1 joule/second =  ?
1. 1 watt
2. 1 ohm
3. 1 ampere
4. 1 coulomb

Answer 1

Correct Answer - Option 1 : 1 watt

The correct answer is 1 watt.

• The correct answer is 1 watt.

• Power:
  • The rate of doing work is called power.
  • SI unit of power is watt named as a respect to the scientist James Watt or Joule Per second and it is a scalar quantity.
    • 1 W = 1 J/s
    • 1 kW = 103 W
    • 1 MW = 106 W
    • 1 Watt/s (W–s) = 1 J
  • Horse power is a practical unit of power.
  • 1 H.P. = 746 watt.
• Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation:
• \(Power = {W \over T}\)

• Ohm is the unit of resistance.
• Ampere is the unit of electric current.
• Coulomb is the unit of electric charge.
