Question

In households, we use parallel electrical connections instead of series, in order to:

• A. Use all appliances at the same voltage
• B. Get the same current though all the appliances
• C. Use all the appliances at their maximum power
• D. Avoid short circuit and overloading

Answer 1

Answer: (A), (C)

The correct options are
A Use all appliances at the same voltage
C Use all the appliances at their maximum power

It is always desirable to get the maximum power from the home appliances. If we connect appliances like fan, light, etc. to the mains in series connection, the current flowing through them would be the same, but their individual power would be reduced.
Instead, if we use parallel connections, each of the appliance gets the same voltage from the mains which makes all the appliances to work at their full power.
