A person hooks a 12 Volt battery to a circuit with a total resistance of 3.5 ohms, what is the current in the circuit?

Use V=IR
In this case:
V=12
R=3.5
So putting it back into the equation:
12=I(3.5)
or
12/3.5 = I
where I = current.
So in turn:
Current =3.428A (Amps)

What a coincidence. There was just another problem with 10 times the voltage and 10 times the resistance in which Ohms law said it is 3.4 amps.
It sounds like a variation of the same homework problem.

v = voltage
r = resistance
i = current
v = r i
i = v/r => i = 12 volts/3.5 ohms = 3.4 amperes

v = i*r
12 = i * 3.5
i = 12/3.5
i=3.429 amperes

V = IR
I = V/R
12/3.5
I= 3.45A
