A) current
(I is always current in electricity)
We would have to use wind or another source
Answer:
When an electric field exists in a conductor a current will flow.
This implies a voltage difference between two points on the conductor.
Electrostatics pertains to static charge distributions.
That means that an object such as a charged spherical conductor will be at the same potential (voltage) on both its outer and inner surfaces.
using the law of refraction, the incidence is equal to the reflection, but not refraction
