Which device is used to measure the electric current flowing through a circuit?

  • AVoltmeter
  • BOhmmeter
  • CGalvanometer
  • DAmmeter
Permalink
Correct Answer: Option D — Ammeter
Explanation: An ammeter is connected in series in a circuit to measure the electric current flowing through it and is designed with very low internal resistance to minimise circuit disturbance.

What does Einstein's mass-energy equivalence equation state?

  • AE equals mv squared
  • BE equals mc squared
  • CE equals half mc squared
  • DE equals mc
Permalink
Correct Answer: Option B — E equals mc squared
Explanation: Einstein's famous equation E equals mc squared states that mass m and energy E are interchangeable with c being the speed of light showing that small masses contain enormous energy.
