Question

an electric heater draws a current of 10A from a 220V supply.what is the cost of using the heater 5hrs per day in the month of April if the cost of 1 unit is 2.50

Answer 1

@apoorvk

Answer 2

cn u do it ma frnd?

Answer 3

cn u do it apoorvk

Answer 4

okay, hmm.
So, Power 'P' = VI

so how what is the power consumption?

Answer 5

??????????????

Answer 6

if i knw dt y shuld i ask u ma frnd??????????????

Answer 7

:D

Answer 8

v=voltage source
I = Current

Can you find the rate of energy being consumed, that is the power 'P'?

Answer 9

Lol, then know this that Power = Voltage x Current being drawn

Answer 10

hhehheheheheehh ma bulb is fused :D

Answer 11

i thnk ur bulb is very powerful sooo plzz do it 4 meee

Answer 12

then please get a new bulb -.-

see, this is a simple formula, please try to get a feel of this!

power consumption will be used for finding the no. of units consumed, and hence the cost.

and,
power = voltage x current = V x I


You have both voltage and current stated above!
(go through the question very slowly and carefully, this ought to help you)

Answer 13

v=220 and l=10
is it?

Answer 14

yes yes, simple as that! now multiply!

Answer 15

220 x 10=2200

Answer 16

nw wt shuld we do
