8- Short and Open in DC series circuit

Описание: Why did my circuit stop working? Did something burn out (open), or did two wires touch accidentally (short)? In this electronics lab, we deliberately break a DC series circuit to see exactly how voltage behaves during these common failures.

[What This Video Covers]
We set up a series circuit with three equal resistors and use ground as our reference point. We then systematically introduce faults to observe the changes on a multimeter.

You will learn:
1- The crucial difference between zero resistance (short) and infinite resistance (open).
2- What happens to the voltage across a component when it is bypassed by a wire?
3- Where the source voltage appears when there is a break in the path, and why the current drops to zero.
4- Why is measuring voltage relative to ground the best way to find where a circuit is broken?

[The Experiment Steps]
1- Baseline: Measure voltages in a healthy 3-resistor series circuit.
2- Creating Shorts: We take a jumper wire and short out R1, then R2, then R3 individually, measuring the voltage at each node to ground.
3- Creating Opens: We physically create a break at R1, R2, and R3 locations, measuring how the voltage distribution shifts dramatically.

[Equipment Used]
1- DC Power Supply (e.g., set to 12V)
2- 3x Equal Resistors (e.g., 2.2kΩ each)
3- Breadboard and Jumper Wires
4- Digital Multimeter
