Understanding the Working Principle of Diodes in Controlling Current Direction

🔍 A diode is an electronic component that allows current to flow in only one direction.

⚡️ Diodes are used to control the direction of current in a circuit.

💡 When a diode is installed correctly in a circuit, it acts as a conductor and allows current to flow.

💡 A diode acts as a conductor when connected in a forward bias and as an initiator in a reverse bias.

🔌 Electricity flows through diodes due to the movement of free electrons.

⚛️ The structure of an atom and its valence shell determine whether a material is a conductor, insulator, or semiconductor.

💡 Silicon is a semiconductor that can act as both an insulator and a conductor.

🔧 Engineers dope silicon with other materials to change its electrical properties and create diodes.

🔌 The structure of a diode consists of p-type and n-type doped silicon layers enclosed in a resin.

💡 A diode has a PN junction, which creates a depletion region of excess electrons and holes.

⚡ When forward biased, a diode allows current to flow if the voltage source is greater than the 0.7 volt barrier.

🚫 When reverse biased, a diode acts as an insulator and prevents the flow of current.

🔎 Diodes are represented with symbols and have technical details that can be found online.

⚡️ Diodes have specific voltage and current requirements for forward bias and act as a conductor or insulator based on the voltage difference across them.

🔌 Diodes are used to control the direction of current flow in a circuit and protect components from incorrect power supply connections.

💡 Diodes can convert AC to DC by allowing the positive half of the sine wave to pass.

⚡ Connecting multiple diodes in a circuit creates a full wave rectifier, allowing both the positive and negative halves of the wave to pass.

🔄 Adding capacitors to the circuit smooths out the ripple and improves the DC supply.

🔴 A diode requires a minimum voltage to open and allow current to flow.

🔄 Reversing the leads connected to the diode should show 'OL' on the screen, indicating that the diode is not functioning properly.

⚡️ To test the diode in a circuit for voltage drop, the multimeter is switched to the DC voltage function and the probes are placed on the appropriate ends, resulting in a voltage reading.
