Question

What is the electric current produced when a voltage of `24 V` is applied to a circuit with a resistance of `32 Omega`?

Answer 1

Data:-
Voltage`=V=24V`
Resistance`=R=32 Ohm`
Current`=I=??`

Sol:-

We know that:
`V=IR`
`implies I=V/R=24/32=3/4`
`implies I=3/4Ampere`

Answer 2

Use the VIR triangle to remember `I = V/R` hence `I = 3/4`A

Explanation:

Use the VIR triangle:

We are given `V = 24`V and `R = 32Omega`, so

`I = V/R = 24/32 = 3/4`A

The VIR triangle can be read as `V = IR`, `I = V/R` or `R = V/I`
