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.
