The current in a simple electrical circuit is inversely proportional to the resistance. The current is 80 amps when the resistance is 50 ohms. What is the current when the resistance is 40 ohms?

I =  / r            where I = current and r = resistance 80 = k / 50 so k = 400 so we have I = 400/r when r = 40   I = 400/40 = 10 amps
