Mobile phone charger output 5 v 1 a==
If I unwrapped cable, 1 k resistor across the line, current is how to calculate?
Is 5 v/1000 Ω=5 ma?

CodePudding user response:

Ma, right, it is 5, 5 v/1 a is when the load is less than 1 a 5 v voltage output, when the load is greater than 1 a will not guarantee the voltage output, could fall to 4 v, 3 v, etc., and even protection,

CodePudding user response:

Can load within 1 a is a voltage source to load

CodePudding user response:

If you pick up the load impedance is small to the current is greater than 1 a then the charger is in CC mode, the output voltage is automatically adjusted
