Question

An electric mortar take 4Ampere from 220 volt line . Find the power of and energy consumed in 3 hours .

Answer 1

Answer:

Explanation:

I = 4 A

V =220v

P = ?

P= VxI

P = 220 x 4

P = 880 W

P = 880/1000

P = 0.880 KW

Now, T = 3 hours

E = ?

E = PxT

E = 0.880x3

E = 2.640 J

Answer 2

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Given :-

Current(I) = 4A

Potential difference(V) = 220v

Time = 3 hours

To Find :-

Power and energy

Solution :-

We know that,

$\huge{\boxed{\boxed{\blue{\sf{P = V \times I}}}}}$

_______________[Put Values]

P = 220 × 4

P = 880 W

Now, we will convert it into Kilowatt per hour.

P = 880/1000

P = 88/100

p = 0.88 KW

$\rule{200}{2}$

We know that,

$\huge{\boxed{\boxed{\blue{\sf{E = P \times T}}}}}$

_____________[Put Values]

E = 0.88 × 3

E = 2.64

$\large{\boxed{\boxed{\red{\sf{E = 2.64 \: J}}}}}$
