so by rearranging the formula resistance = voltage / current. Using the example in Step 1, with a voltage of 50 volts and a current of 2 amps, the resistance is 50 / 2, or 25 ohms.
3. With Ohm's law, if voltage increases and resistance stays the same: current remains the same power decreases current increases resistance decreases 4. Which formula shows a direct proportionality between power and voltage? V = IR P = VI P = IR I = V/R ...
