Voltage and current to electronic devices
Voltage (V): Voltage refers to the electrical potential difference between two points in a circuit. In the context of electronic devices, it represents the force that drives electric current through a conductor. Common voltage ratings for electronic devices include 3.3V, 5V, 9V, and 12V.
Current (A or Amperes): Current is the flow of electric charge in a circuit. It is measured in Amperes (A). The current determines how much charge flows through a conductor in a given time. Electronic devices are designed to operate within specific current ranges.
Ohm’s Law: Ohm’s Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points, and inversely proportional to the resistance (R) between them (I = V/R).
How the 5V2A adapter provides the necessary power
Voltage Output: A 5V2A adapter supplies a constant voltage output of 5 volts. This is suitable for devices designed to operate at this voltage, such as many USB-powered devices.
Current Output: The 2A (2 Amperes) rating indicates the maximum current the adapter can supply. It means the adapter can deliver a current of up to 2 Amperes to the connected device. The device will draw only as much current as it needs, based on its design.
Power (Watts): Power (P) is the product of voltage and current (P = V * I). In this case, the power output of the 5V2A adapter is 10 watts (5V * 2A = 10W). This is the maximum power the adapter can deliver.
Importance of matching the adapter to device requirements
