To solve the problem, we need to understand the role of a fuse in a circuit.
1. Function of a Fuse:
A fuse is a safety device used in electrical circuits to protect against overload and short circuits. It contains a wire that melts when the current exceeds a certain limit, breaking the circuit and preventing further damage.
2. Effect of Overload:
In the case of an overload (when the current exceeds the safe limit), the fuse will blow, preventing further damage to the circuit and other components.
Final Answer:
The usage of a fuse in a circuit prevents $ {\text{Overload}} $.
Determine the equivalent resistance of the parallel combination of the two resistors (X and Y).
Study the circuit shown in which two resistors X and Y of resistances 3 Ω and 6 Ωrespectively are joined in series with a battery of 2V.
Find the current drawn from the battery by the series combination of the two resistors (X and Y).
Study the circuit shown in which two resistors X and Y of resistances 3 Ω and 6 Ω respectively are joined in series with a battery of 2V.
