The number of FM receivers that can be connected to a single FM transmitter depends on several factors, including the transmitter’s power output, the sensitivity and selectivity of the receivers, and the frequency allocation regulations in the area. In general, FM transmitters are designed to broadcast a signal that can be received by multiple FM … Read more
What is the difference between active sensor and passive sensor ? An active sensor emits energy or signals to interact with the environment and detect objects or phenomena. It actively transmits pulses of energy, such as radar or lidar sensors, and analyzes the reflected or emitted signals to gather information. A passive sensor detects and … Read more
To check a run capacitor, you can use a digital multimeter set to the capacitance measurement mode. Start by disconnecting the capacitor from the circuit to ensure accurate readings. Then, discharge the capacitor by shorting its terminals with an insulated screwdriver to prevent any residual charge. Next, connect the multimeter leads to the capacitor terminals. … Read more
Zero ohm resistors, despite their name, are used as jumper wires or bridges in electronic circuits where a connection needs to be made between two points on a printed circuit board (PCB). They have the appearance of resistors but essentially act as electrical pathways with negligible resistance. The primary purpose of a zero ohm resistor … Read more
An electrical motor starter is a device used to start and stop an electric motor safely. It typically consists of a contactor and overload relays or protection devices housed in a single enclosure. The starter controls the motor’s operation by energizing or de-energizing the motor circuit based on commands from a control system or operator. … Read more
Humming in an AC motor can be caused by several factors, with one common reason being mechanical issues such as misalignment of motor components or worn-out bearings. Misalignment can cause the motor’s rotor to vibrate excessively, leading to a humming noise during operation. Similarly, worn-out bearings can produce humming or buzzing sounds as they fail … Read more
Diodes are electronic components that allow current to flow in one direction only. They consist of a semiconductor material with two terminals: an anode (positive) and a cathode (negative). Diodes are used in various applications such as rectification (converting AC to DC), signal modulation, and voltage regulation. They are fundamental building blocks in electronics circuits, … Read more
Inside a microprocessor or integrated circuit (IC), capacitors are essential components integrated directly into the semiconductor substrate rather than being external components mounted on a PCB (Printed Circuit Board). These capacitors are typically formed using layers of conductive and insulating materials within the IC’s structure. For instance, capacitors in ICs can be fabricated using metal-insulator-metal … Read more
The vector group of a transformer refers to the arrangement of windings and their connections in relation to the phase shift between the primary and secondary windings. It specifies how the windings are connected and the angular displacement between them. Each vector group designation represents a specific phasing arrangement that affects the transformer’s performance, particularly … Read more
Zener diodes are heavily doped to achieve a specific breakdown voltage characteristic known as the Zener voltage. By heavily doping both the p-type and n-type semiconductor materials within the diode, the Zener diode can sustain a reverse-bias voltage without breaking down abruptly. This high doping concentration reduces the depletion region’s width, allowing the diode to … Read more
