(1) The product of a volt and a coulomb is a joule.(2) The product of ...
Explanation:
Product of Volt and Coulomb is a Joule:
- The product of a volt (V) and a coulomb (C) is equal to the energy transferred when a charge of one coulomb moves across a potential difference of one volt, which is equal to one joule (J). This is known as the definition of volt.
Product of Volt and Ampere is a Joule/Second:
- The product of a volt (V) and an ampere (A) is equal to the power consumed or generated when a current of one ampere flows through a potential difference of one volt, which is equal to one watt (W). Therefore, the product of volt and ampere is equivalent to one joule per second (J/s).
Product of Volt and Watt is Horsepower:
- The product of a volt (V) and a watt (W) is equal to the power consumed or generated when a potential difference of one volt is applied across a circuit with a power consumption of one watt. This product is equivalent to horsepower, which is a unit of power.
Watt-hour can be measured in terms of Electron Volt:
- Watt-hour is a unit of energy equivalent to the power of one watt consumed for one hour. This can be converted into electron volts (eV), which is a unit of energy commonly used in atomic and nuclear physics.
Therefore, options (1), (2), and (4) are correct as they accurately describe the relationships between volts, coulombs, amperes, watts, joules, horsepower, and electron volts in the context of electrical energy and power calculations.
(1) The product of a volt and a coulomb is a joule.(2) The product of ...
Explanation:
1. Product of Volt and Coulomb is a Joule:
- This statement is correct based on the definition of a joule as the unit of energy. A volt is the unit of electric potential difference and a coulomb is the unit of electric charge. When multiplied together, they result in the unit of energy, which is a joule.
2. Product of Volt and Ampere is a Joule/Second:
- This statement is also correct as the product of volt (electric potential difference) and ampere (electric current) gives power, measured in joules per second (watts).
3. Product of Volt and Watt is Horsepower:
- This statement is incorrect. The product of volt and watt does not result in horsepower. Horsepower is a unit of power equal to 746 watts.
4. Watt-hour can be measured in terms of Electron Volt:
- This statement is correct as watt-hour is a unit of energy equal to one watt of power expended for one hour. It can be converted to electron volts, which is a unit of energy commonly used in atomic and nuclear physics.
Therefore, options (1), (2), and (4) are correct as per the given statements. Only option B states that (1), (2), and (4) are correct.
