If the applied voltage is 80 volts and the resistance is 20 ohms, what is the total current?

Explanation:
Ohm's law links voltage, current, and resistance: I equals V divided by R. With 80 volts across a 20-ohm load, the current is 80/20, which equals 4 amperes. So the total current is 4 A. If you think about the other numbers, 2 A would come from a 40-ohm load, 6 A would require about 13.3 ohms, and 8 A would require 10 ohms, but for 20 ohms the current comes out to 4 A.
