Quiz: name this part in 3 seconds

// QUIZ · PICK YOUR ANSWER

Name this part in 3 seconds! Resistor, diode, capacitor or fuse?

// LESSON NOTES

✅ It's B — a DIODE (this one is a 1N4007: 1000 V, 1 A).

1️⃣ A ONE-WAY VALVE: current flows from the anode to the cathode, and the other way it's blocked. That's how every charger turns AC into DC.

2️⃣ READ THE STRIPE: the silver stripe marks the cathode (−). It matches the bar in the diode symbol, and the triangle points the way current flows.
