Question

an electric iron is marked as 1500 w - 220 v. calculate the current that it draws if it operates at 220 v​

Answer 1

• Power=P=1500w
• Voltage=v=220V
• Current=I=?

We know

$\boxed{\sf P=VI}$

$\\ \sf\longmapsto I=\dfrac{P}{V}$

$\\ \sf\longmapsto I=\dfrac{1500}{220}$

$\\ \sf\longmapsto I=6.8A$
