Question

If resistence of power line is doubled heat energy loss is

Answer 1

Answer:

If the resistance is doubled by applying the constant potential difference the current becomes the half of the previous.

Heat produced, H ∝ I2 . So, when current is doubled the heat produced will be four times.

Answer 2

Energy (power×time) is measured in Joules and by including time (t) in the power formulae, the energy dissipated by a component or circuit can be calculated.Energy dissipated = Pt or VI×tasP=VI.It can also be written as I 2 ×RtasV=IR.Hence, the expression for Power in terms of current is given as P=I 2 RtJ. Therefore, if I becomes 2I, then P ′ =(2I) 2 R×t=4(I 2 R×t).Hence, if the current passing through an electric bell is doubled, the heat produced will become four times more.
