Question

how much current will an electric bulb drawn from a 220 volt source if the resistance of the bulb filament is 1200ohm(b)?​

Answer 1

Explanation:

Here,, Potential Difference,V=220v & Resistance,R=1200 ohm,then Current,I=?

Using ohm's law,

$\mathtt{\boxed{\blue{I=\frac{V}{R}}}}$

$\mathbb{\implies{I=\frac{220}{1200}}}$

$\mathbb{\implies{I=0.183A}}$
