Parallel Combination of Electrical Appliances

When two or more electrical appliances are connected in parallel, they are connected across the same voltage source.

Each appliance is connected to the voltage source through its own separate path.

Each appliance has its own individual current and power consumption.

Total Electrical Power

The total electrical power consumed by the parallel combination of electrical appliances is equal to the sum of the individual power consumption of each appliance.

When appliances are connected in parallel, the voltage across each appliance is the same.

The current consumed by each appliance is independent of the other appliances connected in parallel.

Therefore, the total current consumed by the parallel combination of appliances is equal to the sum of the individual current consumption of each appliance.

Using the formula P = VI, where P is the power, V is the voltage, and I is the current, we can see that the total power consumed by the parallel combination of appliances is equal to:

P(total) = V x I(total)

Since the voltage across each appliance is the same, we can simplify the above equation to:

P(total) = V x (I1 + I2 + I3 + ... In)

Where I1, I2, I3, ... In are the individual current consumption of each appliance.

Conclusion

Since the total current consumption of the parallel combination of appliances is equal to the sum of the individual current consumption of each appliance, the total electrical power consumed by the parallel combination of appliances increases with each additional appliance connected in parallel. Therefore, the correct answer is option A - increases.

In a circuit will parallel resistors the net resistance decreases and according to Ohm's Law, there is an increase in the magnitude of electric current ( I ) because "I"(electric current) is inversely proportional to resistance.
