When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.
- When current flows through loop , it gets conducted.
- Due to this Electric field is generated . This happens due to induced magnetic field.
- The free electrons were at rest until current is there , still ammeter detects some deflection.
- This deflection is due to zero current.
- Due to magnetic field , current in coil changes.
- Mathematically,
- The presence of conducting loop is not necessary for having electric field.
i=0.63 io

Answer:
the property of absorbing light of short wavelength and emitting light of longer wavelength.
Explanation:
YW
It is reflection off of something colored
The electrical force between two charges is given by
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the two charges
We see that the magnitude of the force is inversely proportional to the square of the distance. Therefore, if the distance is increased to 3 times the original distance:
the magnitude of the force will change as
So, the correct answer is <span>
it will decrease to one-ninth the original force.</span>
Answer: The English origin was the largest
