The resistance of a resistor is reduced to half of its initial value. In doing so, if other parameters of the circuit remain unchaned, the heating effects in the resistor will become

Answer»

two times
HALF
one-fourth
four times

Solution :If other parameters of the circuit constant then potential DIFFERENCE due to battery remains unchanged. As heating EFFECT is `H = (V^(2))/(R )t`, hence on reducting resistance to one half of its INITIAL value, the heating effect is doubled.
