Please answer this question. ​

Answer 1

Answer:-

Your Answer Is 3.82 A.

Explanation:-

Given:-

• Power i.e. energy consumption = 840 W.

• Potential Difference = 220 V.

To Find:-

• The current.

Formula Used:-

$\\ \large \orange{ \longrightarrow \boxed{ \purple{ \bf P = VI.}}}$

Where,

• P = Power that is energy.

• V = Potential Difference.

• I = Current.

So Here,

• P = 480 W.

• V = 240 V.

• I = ?? [to find].

Now,

By using formula we get,

$\\ \tt\mapsto P = VI.$

$\\ \tt\mapsto I = \dfrac{P}{ V}.$

$\\ \tt\mapsto I = \dfrac{84 \: \cancel0}{22 \: \cancel0} A.$

$\\ \tt\mapsto I = \cancel \frac{84}{22} A.$

$\\ \tt\mapsto I = \frac{42}{11} A .$

$\\ \large\red{\mapsto \boxed{ \blue{ \bf I = 3.82 \: A.}}} \: \: \: \: \rm(Approx).$

Therefore The current is 3.82 ampere.

So The Final Answer Is Option A.
