First Light
⚡︎⚡︎⚡︎⚡︎⚡︎Every circuit is a loop. Electrons leave the battery’s + terminal, do some work, and must find their way back to −. Wire the lamp into a loop with the battery and let there be light.
📖 The circuit loop
Current only flows around a CLOSED loop: out of the battery’s + terminal, through every part, back into −. Break the loop anywhere and everything stops. That’s all a circuit is — a round trip for charge.
no loop → I = 0
