Question

Calculate the current through a 3.0 ω resistor with a voltage of 9.0 v across it.

Answer 1

Answer: 3 A

Step-by-step explanation:

According to Ohm's law:

`V=R.I`

Where:

`V=9 V` is the voltage

`R=3\Omega` is the resistance of the resistor

`I` is the electric current (the value we want to find)

Isolating
`I`:

`I=(V)/(R)`

`I=(9 V)/(3\Omega)`

Finally:

`I=3 A`
