Science Simulations
You can measure the voltages between 0 and 3.3V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage … more
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 … more
You can measure the voltages between 0 and 16.5V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage … more
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the … more
Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. You can adjust the … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. By applying Kirchhoff’s Law, … more
Description of the simulation You can compare the two cases with each other. The power plant produced is assumed to be \( 22,000V \times 1A = 22,000W \). You can change the voltage and resistance of … more
touch screen The touch screen is a technology that allows you to use IT devices more intuitively by clicking or dragging the desired location on the screen. There are several types of touch screens depending on … more
Multimeter A multimeter is a measuring device that combines various measurement functions such as voltage, current, and resistance. Multimeters are classified into analog and digital multimeters according to how they operate. Analog multimeters were used a … more
Resistance Electrical resistance is a property of a material that impedes the flow of electric current. The unit of resistance is the ohm(Ω). When a voltage of 1V is applied, the conductor’s resistance that allows a … more
In parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of the circuit. If one bulb breaks, the … more
