Hi all and merry Christmas,
I'm new at electronics and thought to use a 240V-50Hz 26VA ac to 12V Max 20.4VA dc transformer to power a breadboard to do some basic series & parallel circuit analysis. I wanted to test the voltage coming out of the transformer with a multimeter, expecting 12v or near. The meter just spikes and shows zero volts yet I plug the leads into the breadboard and it runs a 12v 1.1A fan no problem. Why is there no voltage reading?
When compared to a 12V AA battery configuration, the voltage drops across resistors and LED's differ wildly when using the transformer power supply.
Does the power coming out of a transformer differ from that coming from a battery supply?
Hey thank you to anyone that can enlighten me on the above.
