I have a 230/24VAC transformer followed by a rectifier bridge, if I put the multimetter with the settings on ampers measurement at the + and - terminals,
can I measure the current of this sistem or I will damage the multimetter or the transformer with the bridge?

 

current measurements are done inline not across the terminals.
voltage is measured + to -
