What are Bimetals?
Bimetal Definition
A bimetal is defined as an object composed of two separate metals joined together, retaining their individual attributes.
Properties of Bimetals
Bimetals combine the distinct qualities of each metal into a single functional unit.
Working Principle
imetals bend when heated or cooled due to the different thermal expansion rates of the metals.
l is the initial length of the object,
Δl is the change in length,
Δt is the change in temperature,
The unit of αL is per °C.
Common Combinations
Common bimetal combinations include iron and nickel, brass and steel, and copper and iron.
Applications of Bimetals
Thermostats
Thermometers
Protective devices
Clocks
Coins

Battery charging process using AC adapter
The process of charging the battery using the AC adapter is as followsConnecting devicePlug the AC adapter into the power outlet, making sure the connection is secure and stable. At this point, the AC adapter starts to obtain AC power from the grid.Connect the output of the AC adapter to the device that needs to be charged, usually through a specific charging interface or data cable.Ac adapter operationInput AC conversionThe circuit inside the AC adapter first rectifies the input AC power, conve

The circuit working principle of one-way switch
A one-way switch is the most basic type of switch that has only one input (often called the "normally on" or "normally closed" state) and one output. The working principle of the one-way switch is relatively simple, but it has a wide range of applications in various electrical and electronic devices. The following details the circuit working principle of the one-way switch:The basic structure of a one-way switchA one-way switch usually consists of the following parts: Contact: A metal part used

What is the effect of applying alternating current to a DC machine?
Applying alternating current to a DC motor can have a variety of adverse effects because DC motors are designed and operate to handle direct current. The following are the possible effects of applying AC to a DC motor:Cannot start and run properly No natural zero crossing: AC has no natural zero crossing to help the motor start, while DC motors rely on constant direct current to establish a magnetic field and start. Inversion phenomenon: The sinusoidal waveform of alternating current changes dir
