WebA photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to … WebAug 3, 2024 · Using Ohm's law, we can calculate what they should be. You have 4.5 V available, and the bulb will drop 1.5 V of that when fully lit. That leaves 3.0 V across the resistor. With 3.0 V across it, the resistor should pass 300 mA. (3.0 V)/ (300 mA) = 10 Ω. That's the total series resistance for fully lighting the bulb.
Web1. For limiting current to a certain level, a resistor is used, it is a low-value resistor so that power loss is minimized. 2. If voltage spikes come due to any reason it helps ptevent the LEDs from burning. But if an LED driver is used such resistors are not needed. Share.
