3. FLOWER GLOWING LED:

• Flower glowing LED is an experiment to understand the
working of LED and resistor.
• As the name implies, it look like a flower is glowing.

4. LIGHT EMITTING DIODE (LED)

• It converts Electrical energy into Light
energy.
• LED has a polarity.
• Longer terminal – Positive.
• Shorter terminal – Negative.

5. RESISTOR:

• Resistor helps to resist (or) slowdown the flow of current in
electrical circuits.
• It does not have polarity.

6.

Battery :
Battery is a storage device
It converts chemical energy into electrical
energy
Battery has Polarity
