Question

A fuse wire has .................. electric resistance

Answer 1

Answer:

Low

Explanation:

Low resistance allows maximum current to flow through the wire, avoiding a voltage drop in the circuit.  When excess current passes through the wire, it melts and breaks the circuit

Answer 2

Answer:

Explanation:

ANSWER:

A fuse wire has low electrical resistance.

BUT WHY?

Low electrical resistance in a fuse helps in maximum flow of current, and hence it helps to control the flow of current.

WHAT IS A FUSE?

A fuse is used in a circuit that prevents short circuit and overloading in an  electric circuit by melting itself.

WHAT IS RESISTANCE?

The ability of current to resist the flow is resistance.

The formula of Resistance is

$R = \frac{Rho*l}{A}$

Where rho is resistivity which depends on nature of resistor used

L is length of wire. More length more resistance

A is Area. More Area less Resistance.
