Science Simulations
Battery and Load In an electrical circuit, the battery maintains a voltage difference to allow current to flow through the circuit. In an electric circuit, the place where energy is consumed is called a load. Generally, in school labs, the … more
RLC serial circuit Let’s consider a circuit in which a resistor (R) – an inductor (L) – a capacitor (C) are connected in series. Every moment, the current through the circuit is the same at every point. (It is important, … more
Wheatstone Bridge Electronic measuring instruments like electronic scales detect and measure the resistance change of sensor material. To increase the sensitivity of measuring instruments, it is necessary to measure minute resistance values changes precisely. In this case, the main circuit … more
There are fully charged capacitors. What happens if the capacitor draws current into the inductor? What is the similarity between physical vibration and electrical vibration? LC oscillator An LC circuit(also called a resonant circuit) is an electric circuit consisting of … more
7-segment display, FND Parts that place multiple LEDs to display numbers or hexadecimal characters are called Seven Segment Displays or FND (Flexible Numeric Displays). It can display all numbers from 0 to 9 with only seven LEDs. So, they are … more
The basic structure of the antenna comes from a capacitor. An antenna is a device for sending and receiving electromagnetic waves. A typical dipole antenna has the form of a wire with both ends cut off. The antenna uses these … more

Direct Current, DC In direct current (DC), current flows in only one direction of a conductor. For example, since a battery’s terminals always maintain a constant pole, current flows in only one direction in an electrical circuit. Most of the … more
What if only one switch was installed on the stairs? Suppose there is only one light switch at the top of the stairs. What if You trying to descend the stairs presses a switch to descend the stairs, and then … 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
The structure of the water molecule Water is a representative ‘polar molecule’. The hydrogen-oxygen-hydrogen bonds that make up the water molecule have an angle of 104.5˚ and appear curved. Because of this unbalanced water molecule structure, the oxygen side has … more
