Question

What is the electric current produced when a voltage of `9 V` is applied to a circuit with a resistance of `3 Omega`?

Answer 1

If we apply voltage `V` across a resistor whose resistance is `R` then the current `I` flowing across it can be calculated by

`I=V/R`

Here we are applying voltage of `9V` across a `3Omega` resistor, therefore, the current flowing is

`I=9/3=3` `implies I=3A`

Hence, the electric current produced is `3A`.
