Cheers gneill thanks a lot mate.

R = 360 Ohms Original Resister = 330 Ohms Therefore resistance through the coil = 30 Ohms

resistance = inductance / time constant R = 0.2H/0.55ms R = 36 Ohms Not sure much should much should be ascribed to the new coil, or how this is calculates into the equation

1. An inductor of negligible resistance and an inductance of 0.2 H is connected in series with a 330 Ω resistor to a 12V d.c. supply. Determine: (a) the time constant of the circuit (b) the voltage drop across the inductor after two time constants (c) the voltage drop across the...

I have attempted this question, please feel feel to comment. A horizontal force of 80 N acts on a mass of 6 kg resting on a horizontal surface. The mass is initially at rest and covers a distance of 5m in 0.92 s under the action of the force. Assuming that there is no energy lost to air...
