Current divider

Postby mr light » Sun May 26, 2019 9:59 am UTC

Pls help. Am new to electronics

My Extension socket has values AC127/230-240v, 50/60Hz, 10amax.250

Universal desktop charger has values (input) AC 180-240 50Hz, (output) DC 28-8.7v 250mAH (suitable capacity)200-3000mAH

In the charger's PCB electronic circuit R1,R2,C1, and 1 pin (leg) of its transformer are connected in parallel to the AC v+ (supply).

R1=8.2ohms, R2=3.3kohms, C1=2.2uf (50v), the transformer is a steo down. It has 4 pins in primary coil and 2 pins in the secondary coil ( pls i dont knw its value. u can ignore it)

So how ll electricity b divided among these components in parellel connection to the AC socket supply?

Before anyone can answer this, some things need to be clarified. What's the mains voltage where you live? In the output specs, what exactly does "250mAH" mean (or is it milliamperes rather than milliampere-hours)? I know users with less than five posts can't attach images, but a schematic (or at least pictures of the circuit) would make this a lot easier, particularly with four connections on the primary side of the transformer.
Why do you need this anyway?
