SPDT (single pole double throw) and DPDT (double pole double throw) switches are two typical types of switches used in electronic circuits. The primary difference between the two is the number of poles (the number of individual circuits that the switch can control) and the number of throws (the number of places the switch may be set to). SPDT switches have one pole and two throws, whereas DPDT switches have two poles and two throws. This means that an SPDT switch can control one circuit and can be set to one of two positions, whereas a DPDT switch can control ... Read More

In the world of electronics, power supply plays an essential role. It provides the necessary power for electronic devices to function correctly. The power supply can either be regulated or unregulated. Both regulated and unregulated power supply has its advantages and disadvantages, and it's essential to understand the difference between them to make an informed decision on which type of power supply to use. What is Regulated Power Supply? Regulated power supply is a type of power supply that provides a constant output voltage despite variations in input voltage, load current, and temperature. The regulated power supply has an active ... Read More

Sempron and Athlon are both CPU (Central Processing Unit) product lines manufactured by AMD (Advanced Micro Devices); however, they differ significantly. Sempron is an AMD (Advanced Micro Devices) budget CPU product line designed for cost-conscious users who do not require high-performance computing. Athlon CPUs often feature more cores than Sempron CPUs, which can boost performance for tasks that benefit from numerous cores. Read this article to find out more about Sempron and Athlon and how they are different from each other. What is Sempron? Sempron is an AMD (Advanced Micro Devices) budget CPU product line designed for cost-conscious users who ... Read More

BHP and PS are power units used to measure the output of an engine or motor. PS stands for Pferdestärke, which is German for "horsepower." BHP stands for brake horsepower. The units of measurement are another difference between BHP and PS. PS is measured in metric horsepower (PS or Pferdestärke), whereas BHP is measured in horsepower (hp). Read this article to find out more about BHP and PS and how they are different from each other. What is BHP? Brake horsepower (BHP) is a common measure of an engine's power output in the automotive industry. BHP is the amount of ... Read More

ACPI (Advanced Configuration and Power Interface) and APM (Advanced Power Management) are both power management systems used in computers to control power consumption and maximize energy efficiency. ACPI is designed to handle power management tasks other than basic on/off functions, such as managing system resources, devices, and processor performance. APM is an older and simpler system that provides fundamental power management functions. Read this article to find out more about ACPI and APM and how they are different from each other. What is ACPI? The ACPI (Advanced Configuration and Power Interface) standard was created by Intel, Microsoft, and Toshiba. ... Read More

In a computer system, power supply or power supply unit is a hardware component that supplies required electrical power to other components of the computer system. The power supply unit converts a 220 V AC (Alternating Current) supply into a low voltage DC (Direct Current) supply. The major function that a computer power supply unit performs are − Rectification − Conversion of alternating current supply into direct current supply. Voltage transformation − Decreases the high AC voltage into low voltages. Voltage regulation − Regulates the output voltage to make it constant even when the input voltage is fluctuating. ...

An electric motor is an energy conversion device that converts electrical energy into mechanical energy. Therefore, the input to an electric motor is electricity, while the output of the electric motor is mechanical energy in the form of rotation of the shaft. Based on the type of electrical energy that motor requires to operate, the electric motors are classified into two types, i.e. AC Motor and DC Motor. An AC Motor or alternating current motor is one that transforms electrical energy in the form of alternating current into rotational mechanical energy. On the other hand, an electric motor which transforms ... Read More

In electronics, a device that coverts energy from one form to some other form is known as a transducer. For example, a loudspeaker converts electrical energy into sound, hence it is a transducer. Another common examples of transducers include microphone, thermometer, pressure sensor, antenna and other position sensors, etc. Based on excitation system, transducers are broadly classified into the following two types namely, Active Transducer Passive Transducer The most fundamental difference between active and passive transducer is that an active transducer does not need any external power supply to generate output, whereas a passive transducer needs an additional ...

Volt-Ampere and Watts are power measurement units. Volt-ampere is used to measure the total power that is being consumed by a device. Watts is used to power the device so it can perform its useful work. The product of voltage and current in an AC (alternating current) circuit is known as a unit of apparent power, or VA. It shows the overall power used by a device, which includes both the useful power used and the power lost as a result of inefficiencies like reactive power. The real power used by a gadget to carry out productive work is measured ... Read More

Chain drive and belt drive are the common methods for transmitting power between two spinning shafts in various mechanical systems. Both of these drives are commonly used in applications including autos, industrial machinery, and agricultural equipment to transfer power from one place to another. Belt drive uses pulleys and a flexible belt to transmit power, whereas chain drive uses a metal chain and sprockets to transmit power between two spinning shafts. Read this article to find out more about Chain Drive and Belt Drive and how they are different from each other. What is a Chain Drive? The chain ... Read More
