A Ω of I 0.8 Ampere and works on the 250V on the average 8 hour a day. Find the power and If company charge ₹5 for 6kw/hr what is the monthly bill for 60 days.​

Answer»

Let us take:

Charge or VOLTAGE = V

Current = I  (amp)

Given that:

V = 250 V

I = 0.8 A

Average running time is 8 hours a day

\huge\bf{\mathrm{Solution:}}

Let's calculate the power from the formula....

\huge{\boxed{P = V * I}}

= 250 × 0.8 = 200 W = 200 / 1000  kw

\huge{\boxed{E = P * t}}

= 200/1000 × (8 × 60)

= 0.2 × 480 = 96 kwh

Also given that.

∵ costs is ₹5 for 6kwh

Which can be expressed as..

\huge{\frac{5}{x} = \frac{6}{96}}

Therefore,

⇒ x = 96 x 5 / 6

x = 480 / 6

x = 80

\huge{\boxed{Rupees\;\; 80}}

So the monthly bill for 60 days will be ₹80
