Science Simulations
The above simulation is based on a circuit that actually works. The transistor uses C1815(general-purpose NPN switching transistor). The resistance connected to the base is 100kΩ, and the resistance connected to the emitter is 100Ω. Transistor A transistor is a … more
Diode Diodes are electronic components that pass current in only one direction. The direction in which current can flow through the diode is called ‘forward,’ and the direction in which current cannot flow through the diode is called ‘reverse.’ If … more
LED LEDs are electronic devices that emit photons. LEDs have higher efficiency and longer life than bulbs. Basically, LEDs have a structure like a p-n junction diode. The p-n junction diode is made by attaching a p-type semiconductor and an … more
Transistor There are so many switches inside your computer that you can’t imagine. It’s not the hand-pressed switch we’ve been seeing. It is a switch operated by an electrical signal. The computer counts ‘1’ and ‘0’ according to the voltage … more
