The power generated in the new case is H x n Joules.
It is given that across the same voltage (V), a resistor (R) produces power (H).
If the resistor wire is cut into n parts, the new resistance becomes R / n.
Since power is calculated as the quotient of Voltage squared and Resistance:
Initial power = V^2 / R = H
Final power = V^2 / (R/n) = H x n
