Question

What is the electric current produced when a voltage of `4 V` is applied to a circuit with a resistance of `80 Omega`?

Answer 1

`0.05 \ "A"`

Explanation:

We use Ohm's law here, which states that,

`V=IR`

• `V` is the voltage of the circuit in volts

• `I` is the current produced in amperes

• `R` is the resistance of the current in ohms

And so, solving for electric current, we get,

`I=V/R`

Now, we just plug in the given values, and we get,

`I=(4 \ "V")/(80 \ Omega)`

`=0.05 \ "A"`
