If a 6v incandescent globe is running at 6v with 0.6amps has a 0.909 resistor introduced into it's circuit which drops the voltage across it to 5.501v and 0.55amps how much does the brghtness change?
The Attempt at a Solution
5.501*0.55/6*0.6 original brightness. Is it as simple as this? Because I know globes are a non-ohmic conductor.
