Answer 1

$\huge{\underline{\underline{\purple{\mathfrak{Question :}}}}}$

A geyser is rated 1500W, 250V. It is connected to 250V mains. Calculate

(i) The current drawn,

(ii) The energy consumed in 50 hours, and

(iii) The cost of energy consumed at rupees 2.20 per KWH.

$\rule{200}{2}$

$\huge{\underline{\underline{\purple{\mathfrak{Solution :}}}}}$

♣ Given :-

• Potential Differnece (V) = 250 V

• Power (P) = 1500 W

• Time (t) = 180000 s

____________________

★ Case 1 :-

We know that,

$\Large{\boxed{\pink{\bf{I = \frac{P}{V}}}}}$

(Putting Values)

I = 1500/250

I = 6 A.

$\Large{\boxed{\orange{\bf{I = 6 \: A}}}}$

____________________

★ Case 2 :-

We know that,

$\Large{\boxed{\green{\bf{Energy = VIt \: joule}}}}$

(Putting Values)

Energy = 250 * 6 * 180000 J

Energy = 270000000 J

Energy = 270000000/3600000 KWH

Energy = 75 KWH

$\Large{\boxed{\red{\bf{Energy = 75 \: LWH}}}}$

____________________

★ Case 3 :-

We know that :

1KWH costs Rs 2.20

So,

75 KWH will cost = 75 * 2.2

75 KWH cost = Rs 165

$\Large{\boxed{\blue{\bf{Total \: Cost = Rs \: 165 }}}}$

$\rule{200}{2}$
