Watt's law states the relationships of power to energy.
Answer: Option B
Explanation:
Watt's law gives relationship between power to current, voltage and resistance.
Energy is equal to power multiplied by voltage.
Energy = Power*Time (not multiply by voltage). P = VI. P = (V^2)/R. P = (I^2)*R.
The capacity of a battery is measured in milliamperes.
Battery capacity is measured in ampere-hours (amp-hours)
The power rating of a resistor determines the minimum power that it can handle safely
The joule is a unit of energy.
