Awire with a resistance of 20 ω (ohm's) is connected to a 12-v battery. what is the current flowing through the wire? (blank) amperes

For this particular problem, we use Ohm's Law. This law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR. Using the equation, we can isolate I or the current to one side and the other terms to the other side. We calculate as follows:

V = IR
I = V/R
I = 12 V / 20 Ω
I = 0.6 amperes

Therefore, the current that is flowing through the wire supplied with 12 V and having a resistance of 20 Ω would be 0.6 amperes.
