1.	Question : 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.
Answer» Solution :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`
