What is the function of the load in an electric circuit?
A. The load is the source of the energy.
B. The protons flow through the load.
C. The load is whatever is receiving the energy in the
circuit.
D. The load safely opens and closes the circuit.

The correct answer is the load receives energy and converts in into another form of energy.

Hope it's right and will help you. Thank you

i don't understand. explain it clearly

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
