a circuit It states that the current flowing through a conductor is directly proportional to the voltage applied across its ends and inversely proportional to the resistance Equation I VR Where I Current amperes V Voltage volts R Resistance ohms Practical Applications Calculating the current flowing through a resistor If you know the voltage across a resistor and its resistance you can use Ohms Law to determine the current flowing through it Designing a circuit with a specific current Using Ohms Law you can calculate the required resistance for a circuit to achieve a specific current flow at a given voltage Troubleshooting circuits If a circuit is not working as expected you can use Ohms Law to determine if there is a problem with the resistance voltage or current 13 Kirchhoffs
