Question

Which of the following is the correct sequence in order of increasing power consumption?
A) FAN, TELEVISION, ELECTRIC KETTLE, ELECTRIC IRON
B) FAN, TELEVISION, ELECTRIC IRON , ELECTRIC KETTLE
C) TELEVISION, FAN, , ELECTRIC IRON , ELECTRIC KETTLE
D) TELEVISION, FAN, , ELECTRIC KETTLE, ELECTRIC IRON

Answer 1

Hint: Take the average consumption of power per unit time in increasing order shows which appliances consume more power or electric energy. In our daily uses we know that appliances require more electric energy.

Complete step by step solution:
We know every appliance have different power consumption even different fan have different power consumption, but we take average of it to compare the power consumption by these appliances, on an average fan use $110Watt/hr$, television uses $150Watt/hr$, electric kettle uses $1000Watt/hr$, and electric iron uses $1500Watt/hr$. So if we arrange these power consumption in a sequence in increasing order, we have found that fans have minimum power consumption than others that are given while electric iron has maximum power consumption in given appliances.

Hence option (A) is correct.

Additional information:
In electrical, power consumption refers to the electrical energy per unit time, supplied to operate something, such as a home appliance. Power consumption is usually measured in units of watts \[\left( W \right)\]or kilowatts \[\left( kW \right).\] The energy used by equipment is always more than the energy really needed. The energy used by equipment is always more than the energy really needed. A unit (as mentioned on the electricity bills) is represented in \[kWH\] or Kilowatt Hour. This is the actual electricity or energy used. If you use $1000watts$ or $1$ Kilowatt of power for $1$ hour then you consume 1 unit or \[1~Kilowatt-Hour~(kWh)\] of electricity. There are some other values of power consumption.

Note: Learn the average power consumption of other appliances to deal with such types of questions. You must know that power consumption in home is measured in kWhr.
