Question

A generator 1500W, 250v. This geyser is connected to 250v mains. Calculate (3)

i) The current drawn

ii) The energy consumption in 50 hours

iii) The cost of energy consumed at 420 per Kwh ​

Answer 1

Answer:

the current energy consumed in 50 hours and total cost are 6A,75 KW-h and 165 Rs

Explanation:

given that

power =1500w

voltage =250v

time=50 hours

1) we need to calculate the current the power is defined as

p=vi

where,p=power

v=voltage

l=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=6A

)2)

we need to calculate the energy consumed in 50 hours

the energy is defined as

E=p×t

E=v×i×t

where, t=time

put the value into the formula

E=250×6×50

E=750w-h

E=75kw-h

3) the cost of energy consumed of 2.20 per unit

we need to calculate the total cost

the total cost =2.20×75

total cost = 165 Rs

Hence the current energy consumed in 50 hours and total cost are 6A, 75kw-h and 165Rs
