What is current a flow of?
Current was originally defined as the flow of charges from positive to negative. Scientists later discovered that current is actually the flow of negatively charged electrons, from negative to positive.
What is the current in a wire?
Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR.
Is an Apple charger AC or DC?
I am really not sure what you are talking about…the charger Apple, and all device manufacturers, supply takes house voltage and current (AC) and then supplies it to the device as direct current (DC). DC is the only way the iDevices and MacBook family operate.
Do iPhone Chargers have red and black wires?

What is the output of an Apple charger?
An iPhone charger delivers 5 Watts (5 volts at 1000 mA). A Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA).
Is it OK to charge iPhone with 2.4 A?
When you charge an iPhone, iPad, or computer, you’re resupplying its battery (measured in watt-hours) from a power source like a wall outlet, usually via an adapter. Modern iPhones and iPads support charging up to a current of 2.4A at 5V, while older devices charge around 1A at 5V.
Should you only use Apple Chargers?
It is not necessary to use only an “authentic” charger. What is required is matching the device and the charging protocol it is designed for to a high quality charger with the correct voltages and protocol. The same is true for Samsung and other Android.
Is Fast charging bad for battery iPhone?
Unless there’s some technical flaw with your battery or charger electronics, however, using a fast charger won’t do your phone’s battery any long-term damage. Apple says the fast charger that comes with its iPhone 11 Pro can hit a 50% charge in 30 minutes.
Should I charge my phone every night?
Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.”
