Answer:
<h2>Letter which represent the resistance in this circuit diagram is</h2><h2>D</h2>
Explanation:
Here in this circuit diagram we know that
A = Battery
B = switch
C = connecting Wire
D = Resistance
This zig zag shape is represented as Resistance in all circuits
Answer:
An electric current is said to exist when there is a net flow of electric charge through a region.
Explanation:
In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma

<em>Electromagnetic waves do not need a medium to travel through. </em>
Explanation:
Wave: A wave is a disturbance which travel through a medium and transfer energy from one point to another without causing any permanent displacement of the medium itself.
Waves are classified into two
(i) Mechanical Wave:These are waves that require a material medium for their propagation. E.g water wave, wave generated in a spring, and sound wave.
(ii) Electromagnetic wave: These are waves that do not require a material medium for their propagation. E.g light rays, radio wave, x-rays and gamma rays.
<em>Thus from the above explanation, electromagnetic waves do not need a medium to travel through. </em>
