In an electrical circuit, the current (III) flowing through an LED is determined using Ohm’s Law:
Where:
- I is the current in amperes (A)
- V is the supply voltage in volts (V)
- Vf is the forward voltage of the LED in volts (V)
- R is the series resistor in ohms (Ω)
Write a function that takes supply voltage V, LED forward voltage Vf, and resistor R as inputs and returns the current III.
