Question | Answer |
---|---|
What are conductors? | Objects in which charges (e-s) can move freely through |
What are inductors? | Objects in which charges (e-s) cannot move freely through |
Power dissipated by a resistor | P = I^2 * R |
What is resistance? | A measure of how much an object resists current flow |
What are Kirchoff's Rule? | 1) I in = I out ; 2) Sum of V difference in any loop = 0 |
What are capacitors? | Devices used to store electric energy |
How are capacitors determined? | By geometric effect (i.e., area, diameter, dielectric) |
What is Faraday's Law? | Magnetic flux changes --> current will become induced oppose change |
What is Lenz's Law? | Induced current's magnetic field opposes original change in magnetic flux |
What is an inductor? | A circuit element that uses EM induction to oppose current change |
