In the circuit shows in Fig, the coil has inductance and resistance. When `X` is joined to `Y`, the time constant is `tau` during the growth of current. When the steady state is reached, heat is produced in the coil at a rate `P`. `X` is now joined to `Z`. After joining `X` and `Z`: A. The total heal produced in the coil is `P tau`B. The total heat producd in the coil is `1/2 Ptau`C. The total heat produced in the coil is `2Ptau`D. The data given is not sufficeint to reach a conclusion |
