How many ohms should a cad cell read
Web0.5 Ohms to 600 Ohms: When the oil burner is firing, an ohmmeter reading of 1/2 ohm (close to zero) to a maximum of about 500 to 600 ohms (see note below) is normal. … Web9 feb. 2024 · R = V/I (Resistance = Voltage divided by Current) I – V/R (Current =Voltage Divided by Resistance) So, if you are using a 0.5ohm coil on a battery that gives 4.2 volts, you use the following sum to work out how many amps the circuit is draining from the battery. I = 4.2/0.5 = 8.4A.
