Aim:
To understand how electricity flows through a complete circuit to make an LED glow.
Materials Required:
-
1 × 9V Battery
-
1 × Battery Clip with Wires
-
1 × LED
-
1 × 330-ohm Resistor
-
2 × Jumper Wires
Steps:
-
Connect one jumper wire from the positive terminal (+) of the battery to one leg of the resistor.
-
Attach the other end of the resistor to the longer leg of the LED (positive side).
-
Connect the shorter leg of the LED (negative side) to the negative wire of the battery.
-
If all connections are correct, the LED should glow.
Working of the Circuit:
Electric current flows from the positive terminal of the battery, through the resistor, into the LED, and back to the negative terminal of the battery.
-
The resistor ensures the current is at a safe level for the LED.
-
If the circuit is incomplete or if the LED is connected in the wrong direction, it will not glow.
-
This shows that both the direction of current and a complete path are important for a circuit to work.
