How to measure the amperage in a midpoint trap?
dear cris. you are correct, as the current is equal to the product of the square root of the power (whatts) between the resistance (ohms). if the power has 10w between (1 ohms) the result is equal to ten, the square root of ten is 3.16. you say have 3.5. the measure must be acceptable since it complies with the mathematical norm. test with another transformer. the measure must be taken directly, we have never increased or removed decimales. On Saturday we will make an essay and tell you the result. Greetings . Felipe Ascencio
Dear. I tested with a 2 amp transformer. with central tap. ammeter and focus of 60w in series in a line of ca. by joining the two ends 1.4 amp - by attaching the center tap to either end 0.4 amp. - the fellow electrician comments that before this measure the transformer is not 2 amp.- in the measure of the central tap as you really do not agree, technically could not explain. I hope some teacher would like to contribute data to learn how to know the actual amperage. Greetings. Felipe Ascencio
I tell you I saw a video but did not
specify if I have to add the amper of each end oh so alone
measuring one end I have the total
of amperage? it is understood, for example I have to use two wires one end and the midpoint with a bridge rectifier and a resistance but I do not know if I have to add the amperage that measures in the
two extremes? could you help me with. this question dear friend.
friend tried contacting the midpoint and one end ah bridge rectifier and a resistor of 10w x one ohm in series as it is in the Youtube video and I tried measuring a transformer of an Amper the tester in 10A it measures me three times more because it is an evil calculation in the trafo oh I have to calculate three times less than what the trafo says to me ?? I tried with a 500ma and also
I scored almost two amps ??
I have not seen the video, but if you are using a bridge rectifier, place at the output of the cathodes resistance and in series with this the ammeter in vcd and all to earth, if you use the central tap and one end, connecting the two extremes the measurement has to be the sum of the central tap. check if you are in the correct amperage if your meter has amperage of ca, and cd. Greetings. Felipe Ascencio
Felipe is obvious that if I put a bridge rectifier I am measuring it in DC 10 A now as I will commented comment me measured 3 times
but I already did the test with. a train
of an Amper? It measures me 3,50amper
I ask you why it does not measure me exactly 1amper use a 6 amper bridge a R of 10w x an ohm connect it in series as it has to be you could help me.
