is the answer 33 ohms!

I actually don't know where i got that answer from, my calculations are now something way different. I am completely off track here, I am all confused.

Hmmm, I still get the same answer. Am I along the right track with the equation used?

so, resistance = inductance / time constant R = 36 ohms?

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 resistor after...

Question : A beam 10 meters long, with 3 forces acting on it and 2 re-acting forces on it to keep it in equilibrium. The re-acting forces are at 2 meters from either end. The forces onto the beam are at 3 meters from the left end of 10kN, 10 meters from the left end of 20KN and a distributed...

I have just calculated the bending moment of a beam for every metre over a 10 metre length, the beam is pinned at both ends. Is it possible for the full diagram to be Negative?

Basically I have answered a question using the integration by parts formulae to work out the centre of gravity inside a fan blade using :- v.du/dx = v.u - u. dv/dx with the integral limits of 0 ==> 20 when v = x then dv/dx =1 when du/dx = 0.3 sinx then u = 0.3cos x and sub this into...
