Question 16
F

Two lamps are connected in series. An ammeter before the first lamp reads 0.24 A. What is the current between the lamps, and why?

[1]
A

0.24 A0.24\ \mathrm{A}0.24 A, because charge is conserved through each lamp

B

0.12 A0.12\ \mathrm{A}0.12 A, because each lamp receives half the current

C

0.48 A0.48\ \mathrm{A}0.48 A, because the currents through both lamps add

D

0.00 A0.00\ \mathrm{A}0.00 A, because the first lamp transfers the energy
