I have two different transformers. The output of the first one is 15 volts and 1500 mA. The output of the second one is 5 volts and 500 mA.
If I connected them in series (to get 20 volts) what will happen to the current?
If I connected them in parallel (to get 2000 mA) What will happen to the voltage?
Is there any danger in the previous connections?
