Using Ohm's Law, how much current is going through the following circuit: 12.6 volts, 10 Ohms resistance

Explanation:
Ohm's Law: current equals voltage divided by resistance. With 12.6 volts across a 10‑ohm resistor, I = V/R = 12.6 ÷ 10 = 1.26 amperes. That is the correct current because the ratio of voltage to resistance directly sets how much current flows. If the voltage were higher or the resistance lower, the current would increase; if the voltage were lower or the resistance higher, the current would decrease. For example, 126 amps would need about 1,260 volts across 10 ohms, 0.126 amps would need about 1.26 volts across 10 ohms, and 12.6 amps would need about 126 volts across 10 ohms.
