An electric geyser rated 1500W, 250 V is connected to a 250v line mains. Calculate the electric current drawn by it, energy consumed by it in 50 hours and energy consumed if each unit coast Rs. 6.00.

Text Solution

Verified by Experts

Given P= 1500W V=250V
i) Current drawn `I = (P)/(V)= (1500)/(250)= 6A`
ii) Electric energy consumed by gyser in ` "50 hours" = "Power" xx "time"`
`= 1500 xx 50 = 75000 wH`
Since 1kwh = 1 unit
75kwh = 75units.
Energy consumed = 75 units
iii) Cost of one unit = 6.00
`"Cost 75 units" = 75 xx 6.00 = Rs.450.00`
