This is capacitor replacement tutorial video. This video describes how to replace the damage capacitor with new capacitor. The capacitor has two important reading, they are capacitance and voltage. The capacitance shows how much energy that can hold that given voltage. The voltage reading shows the maximum voltage that capacitor can handle before it exploded. To replace the damage capacitor, […]

This is a voltage divider video tutorial. This video explains about the voltage divider and the use of voltage divider. Voltage divider is the circuit that is used to reduce voltage using resistor. The voltage divider can be used in many things such as to create a point control voltage or generate reference voltage. The following equation defined the output […]

This is a resistor color band tutorial video. This video shows how to calculate the value of resistor using color bands on the resistor. The Resistor has four color bands, the firs three bands show how many ohm the resistor can resisting, and the last bands is the tolerance. The first band is the first digit in how many ohm […]

This is a testing capacitors video tutorial part 2. This Video shows how to check the leakage of the capacitors, the capacity of the capacitors and the breakdown voltage. In this video, to check the leakage of the capacitors, the capacity of the capacitors and the breakdown voltage by using capacitor and resistor analyzer. Just clip the capacitor with analyzer […]

This is a tutorial video of testing capacitors part 1. This video shows how to check the capacitors especially for old capacitors. In this video, the capacitors is checked by using ohmeter. We can know that capacitor is good, dead, or has high leakage after testing the capacitors. The range of ohmmeter is set to maximum range. To check the […]

This is a PCB trace repairing tutorial video. This video talks about how to repair a PCB trace. To repair the PCB trace we can use the conductive pen. First we must shake the conductive pen for 20 second before using it. Then repair the PCB trace. And then we must wait about 24 minutes. The PCB trace has been […]

This is a video tutorial of brushed DC motor basic part 2. This video talks about types of the brushed DC motor. There are four types of the brushed DC motor, they are permanent magnet, shunt-wound, series-wound, and compound-wound. In this video, the advantages and disadvantages are explained in detail. This video also describes the performance comparison of the four […]
