Is diode active or passive ?

A diode is considered a passive electronic component. Passive components are those that do not require an external power source to function or amplify signals. Diodes, including standard rectifier diodes and light-emitting diodes (LEDs), fall under this category. They primarily control the flow of current in a circuit by allowing it to pass in one … Read more

What does an LMP switch do ?

An LMP switch, also known as a Low Voltage Motor Protection switch, is a device used in electrical systems to protect motors from damage due to overload or short circuits. It monitors the electrical current flowing to the motor and automatically disconnects the power supply if the current exceeds a preset threshold. This helps prevent … Read more

Why transistor are called as current controlled devices ?

Why transistor are called as current controlled devices ? Transistors are often referred to as current-controlled devices because their output current (collector current in bipolar junction transistors or drain current in field-effect transistors) is primarily controlled by the base current (in BJTs) or gate-source voltage (in FETs). In bipolar junction transistors (BJTs), the base current … Read more

What is the difference between capacitors and capacitance ?

Capacitors refer to electronic components designed to store electrical energy temporarily. They consist of two conductive plates separated by an insulating material (dielectric). Capacitance, on the other hand, is the property of a capacitor that determines its ability to store electrical charge when a voltage is applied across its terminals. In simpler terms, capacitors are … Read more

What is different between diode and resister ?

A diode and a resistor are fundamental electronic components with distinct purposes and behaviors. A diode is a semiconductor device that allows current to flow in one direction only. It acts as a one-way valve for electric current, allowing current to pass through when forward-biased (positive voltage applied to the anode relative to the cathode) … Read more

What happens if your spark plugs are wet ?

If your spark plugs are wet, it typically indicates that there is excess fuel or oil present in the combustion chamber. This can happen due to issues such as a failing fuel injector, worn piston rings, or improper ignition timing. Wet spark plugs can lead to misfires, rough idling, and decreased engine performance. Whether wet … Read more

Why cant a transformer be used with a direct current ?

A transformer cannot be used with direct current (DC) primarily because of how transformers function based on electromagnetic induction. Transformers operate on the principle of mutual induction between the primary and secondary windings. This induction occurs due to the constantly changing magnetic flux generated by alternating current (AC) flowing through the primary winding. In contrast, … Read more

What is a relay tester?

A relay tester is a specialized device used to verify the functionality, performance, and reliability of electrical relays. Relays are electromechanical switches that control the flow of electricity within a circuit by using a small electrical signal to operate a larger switch. Relay testers are designed to simulate various operating conditions and electrical signals to … Read more

Do power transformers behave as a low pass filter ?

Power transformers do not behave as low-pass filters. A power transformer is designed to transfer electrical energy from one circuit to another through electromagnetic induction. It consists of primary and secondary windings coupled by a magnetic core. The primary function of a power transformer is to change voltage levels (step up or step down) while … Read more
