How Much Current Does it Take to Burn Out an LED?

This video tutorial guides viewers through a project where LEDs are intentionally burned out by using progressively smaller resistors. It covers safety precautions, circuit setup on a breadboard, and using a multimeter to measure voltage. The experiment aims to observe the effects of different resistor values on LED burnout, offering a reverse engineering challenge to create the most spectacular failure.

What is the main purpose of using a current limiting resistor in an LED circuit?

• To make the LED blink

• To change the color of the LED

• To prevent the LED from overheating

• To increase the brightness of the LED

What should you do if you need to disconnect power from the circuit quickly?

• Turn off the switch

• Use tweezers to remove one of the battery wires

• Use your fingers to pull out the LED

• Unplug the multimeter

How is the LED connected in the breadboard circuit?

• With the longer leg connected to the switch

• With both legs in the same row

• With the shorter leg connected to the power bus

• With both legs connected to the ground bus

Why is it safer to measure voltage across the resistor instead of current directly?

• It is easier to connect the probes

• It reduces the risk of blowing the multimeter's fuse

• It prevents the multimeter from overheating

• It provides a more accurate reading

What is the formula used to calculate current using Ohm's law?

• Current = Voltage + Resistance

• Current = Voltage / Resistance

• Current = Voltage - Resistance

• Current = Voltage x Resistance
