Lighting resistor
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.

WebAug 2, 2024 · If, without a resistor in the circuit, the series current would be $1.0\,\mathrm{A}$, and if the resistance of the added resistor equaled the resistance of the light bulb, the current with the resistor in the circuit would be reduced to $0.5\,\mathrm{A}$ everywhere in the circuit.
WebSingle LED Resistor Example. We know that VLED = 3V, V = 9V and I = 35mA. The formula to calculate the resistance value for a single resistor in the above circuit is; R = V – VLED/I. Substitute the values in the above equation to get ‘R-value. R = 9 – 3/0.035 = 171 ohms.
