Which can induce more current in a conductor, a DC current of 50V 10A or a step change from 1mA to 3mA? I thought that in a DC circuit the inductor would not induce a voltage as V=L(δI/δt) where (δI/δt) is 0 for a DC circuit. But then some websites that I have looked at say differently so I'm a bit confused. The question doesn't give me enough information to use any of the equations that I have been taught so could you please tell me how to sove this problem. Thank you.
