Nettet7. nov. 2024 · The source voltage in this circuit is 9 V, the LED’s forward voltage is 2.4 V; so we’ll need 9 minus 2.4 volts to drop across the resistor, which equals 6.6 V. Now Ohm’s law comes into play. We don’t yet know the resistance required for the resistor, but we know the voltage drop across the resistor is 6.6 V and amperage is 0.02 A (20 mA). evangelia theofilis
