WebCycle threshold (Ct) is a numerical value generated during a RT -PCR test. It refers to the number of cycles needed for a sample to amplify and cross a threshold (cut-off) to be considered detected/positive. Most RT-PCR tests use Ct cutoffs of 35 -40 cycles, so any sample with a Ct value below the cutoff, would be considered a true WebThis is why calibration of the CT is generally for a specific type of ammeter. Most current transformers have a the standard secondary rating of 5 amps with the primary and secondary currents being expressed as a ratio such as 100/5. Where: V L is the line-to-line voltage, and V P is the phase-to-neutral voltage. A … Where: N P /N S = V P /V S – represents the voltage ratio; N P /N S = I S /I P – …
