Question

How much current will flow through electric bulb if the resistance is 1200Ohms and PD is 220V​

Answer 1

Given :-

$\pink{Resistance(R) = 1200 Ω}$

$\pink{Potential\:difference (V) = 220 V}$

To Find :-

$\pink{Current(I) = ??}$

Solution :-

$\green{\underline{\underline{We\: know }}}$

$\blue{I = \dfrac{V}{R}}$

$\blue{I = \dfrac{220}{1200}}$

$\blue{ I = 0.18 A}$
