Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change. Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed. The formula can be manipulated so that the relationship can easily be seen for all of the three variables. In this video: I go through practical applications of Ohm's law: current shunt, voltage divider, resistor values for LED, Arduino voltmeter, potentiometer. I demonstrate my Texas Instruments TI-30XS Multiview Calculator which can make calculating formulas a little easier. How to work out resistance in series and parallel? How to work out current in a circuit? What is voltage / volt drop? What is a resistor? Power calculations. How to calculate power in a resistor?
