How do you calculate the resistance

WebJul 7, 2024 · You will find that using a resistor to control the speed of a motor is not the best way. You are losing power to heat in the resistor and you can't actively control the speed while the motor is running. It is better to control it with a PWM square wave signal. You would vary the duty cycle to achieve different motor speeds. WebThe first two digits indicate the resistance value—while the third digit is the multiplier. Resistor color code for 330 Ohms. For example: “482” = 48 x 100 ohms = 4.8 kiloΩ. If the resistors have values less than 100Ω, you can write it as: “480” = 48 x 10 0 (which is equivalent to 1) = 48 x 1Ω = 48Ω or 48RΩ.
