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

Jan 9, 2016

Data:-
Voltage$= V = 24 V$
Resistance$= R = 32 O h m$
Current=I=??

Sol:-

We know that:
$V = I R$
$\implies I = \frac{V}{R} = \frac{24}{32} = \frac{3}{4}$
$\implies I = \frac{3}{4} A m p e r e$

Use the VIR triangle to remember $I = \frac{V}{R}$ hence $I = \frac{3}{4}$A

#### Explanation:

Use the VIR triangle:

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

$I = \frac{V}{R} = \frac{24}{32} = \frac{3}{4}$A

The VIR triangle can be read as $V = I R$, $I = \frac{V}{R}$ or $R = \frac{V}{I}$
