Household power is AC. In contrast, many electronic components are powered by DC power. Therefore, electronic devices such as laptops use a power supply to convert household power to DC. Can you explain how a diode converts AC to DC?
Diode is one of electric parts to allows to flow one driection. Diodes are made by bonding two types of semiconductors. In order for current to flow, what kind of semiconductor should toward to the (+) pole of the battery?
