Why is a closed loop essential in an electrical circuit?
It prevents current from flowing through the circuit.
It provides a continuous return path for current to flow.
It allows current to flow only in one direction without returning.

Transmission Line
The invisible battle inside cables shapes every call and broadcast you make
18 hours ago
0
Why must the wave nature of signals be considered in transmission line design for long conductors?
Because longer conductors always increase electrical resistance linearly.
Because signal reflections and interference can degrade communication quality over long distances.
Because signals behave like direct current and do not exhibit wave properties.

Bi-directional Power Flow
Electricity's new two-way street reshapes energy from passive to interactive
24 hours ago
0
What is a key advantage of bi-directional power flow in modern electrical grids?
It restricts power flow to one direction to ensure grid stability.
It allows energy to be both consumed from and supplied back to the grid, enabling renewable integration and energy storage.
It eliminates the need for power electronics in managing electricity flow.
