Ohms law chart pdf. Ohm s law pie formula chart. Ohm s law formulas there are three forms of ohm s law. Ohm s law combining the elements of voltage current and resistance ohm developed the formula. 480 volts 25 ohms 19 2 amps as you can see when we increase the voltage and leave the resistance the same the current increased directly proportional to the voltage.

In this formula v stands for voltage in volts i stands for current in amperes and r stands for resistance in ohms. When resistance decreases current increases. Introduces the student to basic electricity with an emphasis on ohms law. Just enter 2 known values and the calculator will solve for the others.

Voltage current resistance and power can be calculated using ohm s law. Calculate power current voltage or resistance. Ohm s law ohm s law states that in an electrical circuit the current passing through most materials is directly proportional to the potential difference applied across them. The chart below left shows the relationship between voltage current and resistance.

4 units of measurement 5 proper method to check voltage. Let s say for example that we have a circuit with the potential of 1 volt a current of 1 amp and resistance of 1 ohm. Then select the formula containing the values you know from the corresponding chart quadrant. Below are the formulas for these calculations.
