Question

What is the current in a circuit with a 6.0 V battery and a 2.0 Ω resistor?

Answer 1

Answer: As per Ohm's law current= voltage divided by resistance.

Explanation:

So answer is 6/2= 3 amperes.

Answer 2

For this case, we have by definition, that Ohm's Law states that:

`I = \frac {V} {R}`

Where:

I: It's the current

V: It's the voltage

R: It's the resistance

We have to:

`V = 6V`

R = 2Ω

Substituting:

`I = \frac {6} {2}\\I = 3`

Also, we have that the units of the current, by dividing volts between ohms, will be amps.

Thus, the current is
`I = 3 \ A`

Answer:

`I = 3 \ A`
