Nettet19. jun. 2016 · VRV1 = [RV1 / (RV1 +R LDR1)] × VIN. The above formula can be used for fixed value accurately. However in our case, when the light is detected by the LDR and LED is ON, following is the result: VIN = 9V, RV1 =1kΩ (pot position), VRV1=0.7 V; R LDR1 = 11857 Ω (≈11k Ω -12k Ω) Here we had used a variable resistor RV2 as to … Nettet14. mai 2015 · That would give speed control. With that, you should have a variac that has a zero-output interlock switch. Only energize the motor at zero volts. If you energize a standard permanent magnet 90V DC motor with full voltage, it will appear as a dead short to the supply, since if it isn't rotating, there is no counter EMF to limit the current.
