To find current in a 12v circuit with 3 ohms of resistance you take v/r. That equals current. So 12/3=4 so 4 amps. The second half of your question is similar. P/V is what we will use to answer this. 60/120.
So that comes to .5 amps. Look up ohms law. That is how to find answers like that for electrical circuits.
