Problem 60795. Ohm’s Law - Calculate Resistance

Created by karthik kumar k

Solve Later

Ohm’s Law states that resistance R can be calculated as:R=V/I​
where:
V is the voltage (in volts)
I is the current (in amperes)
R is the resistance (in ohms)
Write a function to compute resistance given voltage and current.

This formula is incorrect. It calculates power rather than resistancee.

@William no, the formula is correct*
Resistance = Voltage / Current
The general formula for electrical power is:
Power = Voltage * Current
(at least in DC, more complicated in AC)

The test suite is far too small, nowhere near comprehensive enough.
At the moment, any solution that returns 0 will pass.
Need to add more tests, such as V = 10, I = 11.

I recently finished this problem. Future people, remember that you're solving for the RESISTANCE. Don't overthink it.
