Question

A geyser is rated 1500w ,250v .This geyser is connected to 250v mains .Calculate the energy consumed in 50hrs

Answer 1

Answer:

The current,energy consumed in 50 hours and total cost are 6 A, 75 kW-h and 165 Rs.

Explanation:

Given that,

Power P = 1500 W

Voltage V = 250 V

Time t = 50 hours

(I). We need to calculate the current

The power is defined as,

P= V x I

Where, P = Power

V = voltage

I = current

The current is equal to the power divided by the voltage.

I = P / V

Put the value in to the formula

I = 1500 / 250

I = 6 A

(II). We need to calculate the energy consumed in 50 hours

The energy is defined as,

E = P x T

E = V x I x T

Where, T = time

Put the value into the formula

E = 250 x 6 x 50

E = 75000W - h

E = 75 KW - h

(III). The cost of energy consumed of 2.20 per unit.

We need to calculate the total cost

The total cost =  2.20 x 75

Total cost =165 Rs.

Hence, The current,energy consumed in 50 hours and total cost are 6 A, 75 kW-h and 165 Rs.
