today's quick tip is on how to measure small signals in a circuit. you will employ the use of what's called a voltage follower. this is a configuration of an operational amplifier so that the voltage input will equal the voltage output. however, they output voltage will be a mirrored voltage coming from the op amps own supply. therefore, when you measure the output of the voltage follower, you are drawing current from the operational amplifier and not from the circuit your measuring
