Question

What a heating device is connected to 230 volt supply 0.4 current flows through it. Find the resistance of the heating coil?

Answer 1

• Voltage=230V=V
• Cureent=I=0.4A
• Resistance=R=?

Using ohms law

$\boxed{\sf \dfrac{V}{I}=R}$

$\\ \sf\longmapsto Resistance=\dfrac{230}{0.4}$

$\\ \sf\longmapsto Resistance=575\Omega$
