WebMay 3, 2016 · So my DC motor is 9v, but if I use a 10k potentiometer, there is a big voltage drop across it and the motor barely gets any voltage. And since power is currentXvoltage, the motor isn't powerful enough because there is not enough voltage getting to it.

WebStep 7: Adjust the potentiometer mechanism until the voltmeter registers exactly 1/3 of the total voltage. For a 6 V battery, this will be approximately 2 V. Step 8: Now, connect two … WebCalculate the resistance of the DC motor using the ohms law formula: resistance (R) = voltage (E) / current (I) . For this fan, it would be R = 14/0.08. Solving this equation, you get a resistance of 175 ohms. This tells you the nominal resistive value of the potentiometer you need, and the 0.96 watts tells you the minimum required wattage.
