Question

On a dry winter day, you scuff your leather-soled shoes across a carpet and get a shock when you extend the tip of one finger toward a metal doorknob. In a dark room, you see a spark perhaps 5mm long. Make order-of-magnitude estimates of (a) your electric potential

Answer 1

Therefore electric potential is V = 15000V.

What is electric potential?

The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential).

length of sparks d = 5 mm = 5 x 10^-2 m

(a) It is possible to find average values for the skin's surface and the electric field in dry air from outside sources. Electric field and spark length can be used to determine electric potential.

V = E.d

V = 15000V
