Key Points:
- The unit of energy is joule (J).
- Newton metre (N.m) is the unit of torque or work.
- Kilowatt hours (kWh) is the unit of electrical energy.
- Kilowatt (kW) is the unit of power.
Explanation:
The unit of energy is the joule (J). It is a derived unit in the International System of Units (SI) and is defined as the amount of work done when a force of one newton is applied over a distance of one meter.
Units Explained:
- Newton metre (N.m): This is the unit of torque or work. It represents the amount of work done when a force of one newton is applied over a distance of one meter. It is not a unit of energy.
- Joule (J): This is the unit of energy. It is defined as the amount of work done when a force of one newton is applied over a distance of one meter.
- Kilowatt hours (kWh): This is the unit of electrical energy. It represents the amount of energy consumed or produced by a device with a power of one kilowatt over a period of one hour. It is commonly used to measure electricity consumption in homes and businesses.
- Kilowatt (kW): This is the unit of power. It represents the rate at which energy is consumed or produced. One kilowatt is equal to 1000 watts.
Conclusion:
The unit of energy is the joule (J). The Newton metre (N.m) is the unit of torque or work, the Kilowatt hours (kWh) is the unit of electrical energy, and the Kilowatt (kW) is the unit of power. Therefore, the correct answer is option B, which states that (a), (b), and (c) are correct.
