Plz let me knw the answer of que10.....
Parul took a wire of length 10cm .binu took a wire as shown in the circuit given in the figure .the current flowing in both the circuits is the same.
I. Will the heat produced in both the cases be equal ? Explain.
2. Will the heat produced be the same if the wires taken by them are of equal length but of different thickness ? Explain.

i-) No, the heat produced in both cases will not be equal.
The first resistor of length 10cm has more resistance than the second resistor of length 5cm since resistance is directly proportional to its length.
So, by using the formula P= I^2R, P will be more in case of the first resistor.
ii-) No, even if the lengths of the resistors will be equal, their thicknesses are different due to which their resistances will differ as well.
