Answer :
As additional branches are added to a parallel circuit, total circuit resistance decreases.
What is circuit resistance?
The obstacle to the flow of charge is resistance. An electron cannot travel in a straight line from one terminal to the next. Instead, a zigzag path is created by several collisions with stationary atoms in the conducting substance. The movement of the electrons is hampered by resistance. Resistance prevents the passage of charge, whereas the electric potential difference between the two terminals promotes it.
What is parallel circuit?
In parallel circuits, various components are connected on various branches of the cable. If you follow the circuit diagram from one side of the cell to the other, you will only be able to travel through each of the numerous components by taking all of the branches.
The components on the other branches of a parallel circuit continue to operate even if a lamp goes out or a component is unplugged from one parallel wire. Additional lamps may be added concurrently.
