This can be somewhat misleading. If it’s a two-wire (line powered) transmitter and it is sourcing its maximum loop current of 20ma, 5VDC is dropped across the 250 ohm resistor. E = I x R = 20ma x 250 ohm = 5VDC That only leaves 7 volts to operate the transmitter. how much kombucha should you drink daily
