The red, white and green wires in a phone charger are the positive, negative and ground wires, respectively.
The red wire is the positive wire, which carries the power to the phone.
The white wire is the negative wire, which returns the power back to the charger.
The green wire is the ground wire, which helps to protect the phone from electrical surges.
What is the purpose of red wire in charger
The purpose of the red wire is to provide a positive connection to the charging circuitry. This allows the charger to properly deliver power to the device being charged. Without this connection, the charger would be unable to function correctly.
What is the purpose of green wire in charger
The purpose of green wire in charger is to provide a return path for the current. When the charger is connected to an AC outlet, the green wire allows the current to flow from the outlet back to the charger. This enables the charger to work properly and prevents damage to the electrical components.
