V = I R, so that 60 = I x 12, re-arrange the formula...
I = V / R, or I = 60 / 12 which equals 5A.
So it's B.

The basic law of electricity is the ohms law which says that voltage is proportional to current flowing through a circuit
or mathematically V=I*R
(where V is the potential difference or voltage
I is the current flowing through the circuit
& R is the resistance of the circuit)
so applying the above expression
V=60 volts=(12 ohms)*(I amp)
or 60 volts/12 ohms= I amp
5/1=I amp therefore the current flowing through the circuit is 5 amps i.e. your choic no A
(thank you)

Ohm's law states that V=I*R, where V is the voltage, I the current and R the resistance. Simple substitution gives us 60=I*12, and from that we can rearrange the equation so that I=60/12, therefore I (the current, remember?) must be 5 amps.

The current flowing throught the circuit is 5A as I=V/R. V = 60v and R = 12 so it's 60 divided by 12 = 5.... so the answer is 5A ... or (B).......simple

The answer is 5 amps.
E=IR I=E/R, so 60/12=5

B. 5 A
Remember: Ohms = Volts / Amps right? so...
12 ohms = 60 Volts / X amps ... so X has to be 5.
