‘The wire of greater resistance produces greater amount of heat ...
Explanation:
Resistance and Heat Generation:
When an electric current passes through a wire, resistance in the wire causes some of the electrical energy to be converted into heat energy. This is due to the collision of electrons with atoms in the wire, which generates heat. The amount of heat produced is directly proportional to the resistance of the wire.
Relationship between Resistance and Heat:
- The statement "The wire of greater resistance produces a greater amount of heat energy" is true because a wire with higher resistance will impede the flow of current more than a wire with lower resistance. As a result, more electrical energy will be converted into heat in the wire with greater resistance.
- This can be explained by the formula for power dissipation in a resistor, which is given by P = I^2 * R, where P is power, I is current, and R is resistance. From this formula, it is evident that power (heat) generated is directly proportional to resistance.
Practical Implications:
- In applications where heat generation is desired, wires with higher resistance are used to ensure efficient conversion of electrical energy into heat.
- Conversely, in applications where heat generation needs to be minimized, wires with lower resistance are preferred to reduce energy loss and heat production.
Conclusion:
In conclusion, the statement that "The wire of greater resistance produces a greater amount of heat energy" is true due to the direct relationship between resistance and heat generation in an electric circuit. Understanding this relationship is crucial in designing circuits for specific applications where heat dissipation is a critical factor.
