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
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
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
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 the switch after fully … 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 the transmission line respectively. … 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 the detection method. Resistive … 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 lot in the past, … 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 current of 1A is … 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 bulbs in the other … more

Resistance is analogous to a toll-gate, meaning that it limits the flow of current. Please note that excessive analogy may cause misconceptions. (The cars in the simulation are crowded out, but the actual charges are evenly distributed throughout the conductors.) … more
What is the voltage value of the voltmeter? Voltage distribution in series connection When two or more resistors are connected in series, the sum of the resistors’ voltages becomes the total voltage. Therefore, the resistors divide the supplied voltage according … more
