A. The other terminal of the cell ✓ Correct
B. Nowhere, it just stops
C. The same terminal it left from
D. The bulb, where it stays
Solution: Current flows out from one terminal, through the circuit, and back into the other terminal of the cell.
Q18 — Electric Circuits · hard · theory

A. The circuit is too small
B. The cell (battery) is used up ✓ Correct
C. The wires are too short
D. The bulb is too shiny
Solution: If everything is connected but the bulb stays off, the cell has most likely run out of energy.

A. Our body can conduct electricity, so touching wires with wet hands is dangerous ✓ Correct
B. Wood is a good conductor
C. Copper is an insulator
D. Our body cannot conduct electricity at all
