A Sinusoidal wave in the context of Electrical or Electronics Engineering is used to represent a time-varying voltage or current whose average value in...
Alternating Voltage (AC Voltage): Voltage that changes direction periodically, usually in a sinusoidal pattern.
A sine wave represents AC voltage and current.
Voltage and current rise...
As you can see, the current through the coil is 90° out of phase - and delayed. Why? The periodically alternating current flow...
An ultrasonic sensor is a device that measures distance or detects objects by sending out ultrasonic sound waves and measuring the time it takes...
Pressure Sensors measure the force exerted by a fluid (liquid or gas) and convert it into an electrical signal.
Common types:
Strain Gauge Sensors – detect...
Temperature Sensors measure heat or cold and convert it into an electrical signal. Common types include:
Thermocouples – generate voltage based on temperature difference.
RTDs (Resistance...
Photoelectric Sensors can be used to detect objects or the orientation of an object on a production line, and they can be used to...
A PIR (Passive Infrared) sensor detects human presence by sensing infrared (IR) radiation emitted by the body. When a person moves within its range,...
Inductive Sensors Used to detect metal objects without contact. Work by generating an electromagnetic field → when a metal object enters, it changes the...
Resistors in Series
The same current flows through each resistor one after another.
Total resistance is the sum: R_total = R1 + R2 + R3 +...
Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures...
Symptoms of Chronic Hives
Chronic hives, also known as chronic idiopathic urticaria, are characterized by red, itchy, raised welts on the skin, often called wheals....
