An electric iron connected to a 110-V source draws 9 A of current. Show that the amount of heat it generates in a minute is nearly 60,000 J.
Solution 8P Step 1 : We need find the amount of heat generated in a minute Considering the data given Voltage v = 110 V Current I = 9 A Step 2 : Let us find power in terms of watts It is given as watts = volts × amp Let us substitute the value for volt and amp we get watts = 110 volts × 9 amp Hence we get watts = 990 watts This can also be written as 990 J/s
