Divider law for voltage and current. series same current. voltages add up. parallel currents add up. same voltage. I'm surprised to find the topic suddenly shifting tooperational amplifier. Isn't that much more complicated? I get it. Itdoesn't matterwhat anop ampis or how it works inside...

connection. The voltage divider is in serial connection with the test object and used for measuring the resonance voltage and acting as the overvoltage protection signal. The frequency modulation power output is coupled to series resonance circuit via excitation transformer to provide the exciting ...
The circuit in Figure 12 shows a k-type thermocouple going through a 54dB gain stage to channel 1 of the MAX110. A MAX874 voltage reference provides both the 3V reference voltage and reference junction temperature information to the MAX110. Armed with the temperature information provided by ...
