# In meter bridge apparatus the bridge wire possess

$(a)\;\text{High resistivity and two temperature coefficient} \\(b)\;\text{High resistivity and high temperature coefficient} \\(c)\;\text{Low resistivity and high temperature coefficient}\\(d)\;\text{Low resistivity and two temperature coefficient}$
Can you answer this question?

The meter bridge wire should have high resistivity and low temperature coefficient .
So that it does not get heated up it when current passes through it.
Hence a is the correct answer.
