## 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

## 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

## Electric Circuit Simulator (AC)

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, accurate measurements can be … more

## Electric Potential 3

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

## Ohm’s Law

Ohm’s Law When you connect the light bulb and the battery with a wire, the bulb lights up. This is because free electrons with negative charges (-) move along the wire, and this flow of charges is called current. It … more

## Wheatstone Bridge

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

## Capacitor

Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. The capacitor is made … more

## 7-segment display(FND)

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

## Stair Switch

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
