Hi,
There is something I want to ask about the circuit that I share.The circuit is used to control a motor(draws about 30 amps.)
my question is this circuit how to measure current , what I understand is that the current is measured by raising the voltage on the resistor with the op-amp. but Why power line like this , Is there a shunt res which one is it?
I can not explain exactly, but if you understand something from these pictures, please help.
