A cell, a lamp and a resistor are connected in a single closed loop.
The current in the lamp is 0.30 A.
What is the current in the resistor?
0.15 A0.15\ \text{A}0.15 A, because the current is shared between the two components
0.30 A0.30\ \text{A}0.30 A, because the current is the same at all points in the loop
0.60 A0.60\ \text{A}0.60 A, because the currents in the two components add together
Less than 0.30 A0.30\ \text{A}0.30 A, because the lamp uses up some of the current
