If a resistor has 2 ohms resistance and 6 volts across it, the current is?

Explanation:
Current equals voltage divided by resistance. With 6 volts across a 2-ohm resistor, the current is 6 V / 2 Ω = 3 amperes (3 A). If the current were 1 A, you’d need 6 Ω of resistance; for 12 A you’d need 0.5 Ω; for 0.5 A you’d need 12 Ω. The given voltage and resistance directly yield 3 A, so that’s the correct result.
