Aspark plug in an automobile engine consists of two
metalconductors that are sparated by a distance of 0.75mm. when
anelectric spark jumps between them, the magnitude of the
electricfield is 4.7 x 10 to the 7th v/m. what is the magnitude of
thepotential difference (delta v) between the conductors?

Electric potential,

Explanation:

It is given that,

The magnitude of electric field,

Distance between automobile engines that consists of metal conductors,

Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:

So, the magnitude of the potential difference between the conductors is . Hence, this is the required solution.

answer: 0

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
