This relationship is given by the equation V = R * I , where V stands for voltage (measured in volts), R is resistance (measured in ohms), and I is current (measured in amperes).
"T5D02: What formula is used to calculate voltage in a circuit?" The answer is 'A', E = I x R. |
When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω. Named for German physicist Georg Ohm (1789-1854), Ohm's Law ... |
The formulas covered include V=IR for voltage, I=V/R for current, R=V/I for resistance, P=VI for power with voltage and current known, P=I^2R for power with ... |
The voltage (or potential difference) between two points in a circuit is the work done per unit charge as the unit charge moves between those two points. |
