When the resistors are connected in parallel their combined resistance os less than the least individual resistance ,thus the current drawn is more and hence power os more

Parallel Combination of Electrical Appliances and Total Electrical Power



When electrical appliances are connected in parallel, they are connected across the same voltage source, with each appliance having its own separate pathway to the power source. In a parallel combination, the positive terminals of all appliances are connected together, and the negative terminals are connected together. This configuration allows each appliance to operate independently, without affecting the others.

Increase or Decrease of Total Electrical Power



The total electrical power in a parallel combination of electrical appliances may decrease compared to the power consumed by a single appliance. This is because the total power consumed by the combination is determined by the sum of the individual powers of each appliance.

Explanation:



1. Power Consumption of Appliances


Each electrical appliance has a specific power rating, which indicates the amount of electrical power it consumes when operating. The power rating is usually specified in watts (W) or kilowatts (kW). For example, a light bulb may have a power rating of 60W.

2. Power Calculation


In a parallel combination, the total electrical power consumed by the appliances is calculated by summing up the power ratings of all the appliances connected in parallel.

3. Independent Operation


Each appliance in a parallel combination operates independently, meaning that the power consumed by one appliance does not affect the others. Therefore, the total power consumed by the combination is determined solely by the power ratings of the individual appliances.

4. Total Power Consumption


When appliances with different power ratings are connected in parallel, the total power consumption of the combination will depend on the specific power ratings of the appliances. If the power ratings of the appliances connected in parallel are lower than the power rating of a single appliance, the total power consumed by the combination will be lower than that of a single appliance.

5. Example


For example, if a 60W light bulb and a 40W fan are connected in parallel, the total power consumed by the combination will be 100W (60W + 40W), which is less than the power consumed by the 60W light bulb alone. This demonstrates that the total electrical power in a parallel combination can decrease compared to a single appliance.

Therefore, in a parallel combination of electrical appliances, the total electrical power decreases compared to the power consumed by a single appliance.
