In LEDs, the longer lead (wire) is always connected to the _______ terminal
- a)negative
- b)neutral
- c)positive
- d)Any terminal
Correct answer is option 'C'. Can you explain this answer?

In LEDs, the longer lead (wire) is always connected to the _______ ter...
In LEDs, the longer lead (wire) is always connected to the positive terminal. This is because LEDs are diodes, and they only allow current to flow in one direction. The longer lead is the anode (positive terminal), and the shorter lead is the cathode (negative terminal).

Understanding LED Leads
LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them. They have two leads, which connect to different terminals in a circuit.
Lead Length Significance
- The longer lead of an LED is known as the anode.
- The anode is always connected to the positive terminal of the power supply.
Why the Longer Lead is Positive
- Polarity in LEDs: LEDs are polarized components, meaning they must be connected to a power source in a specific way for them to function correctly. Connecting them incorrectly can damage the LED or prevent it from lighting up.
- Current Flow Direction: Current flows from the positive terminal (anode) to the negative terminal (cathode). The longer lead being the anode ensures that the current can flow into the LED correctly, allowing it to emit light.
Identifying LED Leads
- Long Lead: Connects to the positive terminal.
- Short Lead: This is the cathode, which connects to the negative terminal.
Conclusion
Understanding the polarity of LEDs is crucial for their proper operation. By ensuring the longer lead is connected to the positive terminal, users can enjoy the full functionality of their LED devices, whether in simple circuits or more complex applications.
