What are the Ohm's Law equations? | E = voltage I = Current R = resistance E = IxR I = E/R R = E/I |
Define resistance | Resistance is the inability of a part of a curcuit to allow the passage of a direct (constant voltage) current. |
Define impedance | Impedance is the resistance of a part of a circuit to the passage of an alternating current |
E = IxR | E = voltage I = Current R = resistance |
I = E/R | E = voltage I = Current R = resistance |
R = E/I | E = voltage I = Current R = resistance |
