| Ohm's law |
The relationship that exists between the electrical parameters of voltage (electrical pressure), resistance (the opposition to the voltage), and current (the flow of electrons in the circuit). Ohm's Law states that the amount of current flowing in a circuit is equal to the applied voltage divided by the circuit resistance.

| Ohm's law |
The basic math needed for nearly all electrical calculations. Please see a dictionary or Pocket Ref for all of the variations on Ohm's Law! E=I*R (voltage(E)=amperage(I)*resistance(R)), and all of the algebraic variations of this (I=E/R, R=E/I). Also, for DC circuits, Watts=Volts*Amps. For AC circuits, Watts=Amps * Volts * Cosine of phase angle theta.

| Ohm's law |
The basic relationship between current, voltage, and resistance. Ohm's law states that voltage = current x resistance, current = voltage/resistance, and resistance = voltage/current.

| Ohm's law |
The statement of relationship between current, voltage, and resistance. Where I = Current, E = Voltage, and R = Resistance, I=E/R, E=IR, and R=E/I. The equation for calculating resistance in series is R 1 + R 2 + ... + R n = R total . The equation for calculating resistance in parallel (eg for speakers and subwoofers) is 1/R 1 + 1/R 2 + ... + 1/R n = 1/R total

| Ohm's law |
states that the current in a metallic conductor is equal to the potential difference between the ends of the conductor divided by its resistance; symbolically, I = V/R.
