Re: Circuit Lab B/C

Ok, here are some easy ones since I can't think of any hard ones: 1) What direction do electric field lines created by a stationary proton point? 2) Do ferromagnetic metals retain their magnetic property? If not, state what needs to happen for its magnetic property to be "activated." 3) A...

Re: Circuit Lab B/C

Define impedance and explain what it is used for. Impedance is the complete opposition of the flow of current, unlike resistance, which only slows the speed of the flow of current. It is commonly described as the "resistance to AC current." It is used in capacitors and inductors in the fo...

Re: Sounds of Music C
