Question 1 of 10
What is the primary source of an electric field?
Electric fields are generated by both stationary charges and changing magnetic fields.
Question 2 of 10
What is the unit of measurement for electric field intensity?
Electric field intensity is measured in Newtons per Coulomb (N/C) or Volts per meter (V/m).
Question 3 of 10
What is the unit of measurement for magnetic field strength?
Magnetic field strength is measured in Tesla (T) or Gauss (G).
Question 4 of 10
In what direction do electric field lines originate and terminate?
Electric field lines originate from positive charges and terminate at negative charges.
Question 5 of 10
What happens to the electric field strength as the distance from a source charge increases?
Electric field strength decreases with the square of the distance from the source charge.
Question 6 of 10
What is the relationship between electric and magnetic fields produced by a moving charge?
A moving charge produces both electric and magnetic fields that are mutually perpendicular.
Question 7 of 10
What instrument is used to measure an electric field?
An electrometer is used to measure an electric field.
Question 8 of 10
What instrument is used to measure a magnetic field?
A magnetometer is used to measure a magnetic field.
Question 9 of 10
Electric field intensity is defined as?
Electric field intensity is the force per unit charge.
Question 10 of 10
