## Same Circuit

Same Circuit In an electric circuit, voltage occurs at both ends of the cell. The place where this voltage is released is called ‘load’. In typical textbooks, ‘load’ is often replaced by a light bulb or resistor. Since a typical … more

## Potentiometer

Potentiometer The potentiometer is an electronic component that allows you to adjust the resistance value freely. The potentiometer is used to adjust the volume of sound in audio equipment and so on.   How is the structure of the potentiometer? … more

## Home Wiring (Indoor Wiring)

Build the indoor wiring to make the electric appliance work. Home wiring All electrical devices have a resistance value, and this resistor limits electric current. A power strip or indoor wiring is a parallel connection of resistors also. The electrical … more

## Incandescent light bulb (heat dissipation of resistance)

Resistance Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and allow current to flow … more

Half Adder An adder is a logic circuit that can perform additional operations on binary numbers. It can be composed of only three types of logic circuits: AND, OR, and NOT gates. Bit addition is handled with an XOR gate … more

## Logic Gate

Logic Gate Logic circuits are responsible for arithmetic operations in a computer. All numbers are converted to binary for the logic circuit to work. A binary number is a number system that consists only of the numbers ‘1’ and ‘0’. … more
