Question

Find the current passing through a circuit consisting of a battery and one resistor. The resistor has a resistance of 2 ohms and the battery has a voltage of 12 volts.

A) 0.167 amps
B) 2 amps
C) 6 amps
D) 8 amps

Answer 1

The current flowing in the circuit can be found by applying Ohm's law:

`V=IR`
where
V is the voltage of the battery
I is the current flowing in the circuit
R is the resistance of the circuit

In our problem, V=12 V and
`R=2 \Omega`, so if we re-arrange the previous equation and we use these data, we find the current in the circuit:

`I= (V)/(R)= (12 V)/(2 \Omega)=6 A`

Therefore the correct answer is C).
