Please Help!!! Inductor Circuit An AM radio antenna has the shape of a coil with inductance 0.90 mH. A radio wave with frequency 1.2 MHZ induces a current of amplitude 5.2 nA in the coil. What is the amplitude of the induced voltage across the coil? I really need your help. It's going to be on the test for tomorrow. Thanks in advance. This is what I did, I'm not sure of it. First, we get "w" from the frequency from equation w=2*Pi*f. Next we find the reactance of the inductor as it matches the resistor. XL=wL which eqauls the resistor R. Then the induced voltage is simply V=IR. We already have the current and we calculated R. Am I right? Please Help me out.
