The lead wires should have
Text Solution
Verified by ExpertsThe correct answer is:
A
Explanation:
In a circuit, lead wires are used to connect various components. Their characteristics can significantly affect the performance of the circuit.
Therefore, lead wires should have a larger diameter and low resistance for efficient operation. Thus, the correct option is A.
In a circuit, lead wires are used to connect various components. Their characteristics can significantly affect the performance of the circuit.
- Resistance: Lead wires should ideally have low resistance to minimize voltage drops and power losses.
- Diameter: A larger diameter of the wire decreases its resistance according to the formula:
$$ R = \frac{\rho L}{A} $$
where R is resistance, \rho is resistivity, L is the length, and A is the cross-sectional area. A larger cross-sectional area (which is related to a larger diameter) will result in a smaller resistance.
Therefore, lead wires should have a larger diameter and low resistance for efficient operation. Thus, the correct option is A.
