No, I measured the readings with a digital multimeter too. OK so let me get everything straight for myself ... a bit confused here.
The transformer is a stepped-down transformer (230V to 12V). When the transformer says that it stepped-down the value from 230V to 12V it means that that 12V is...
I re-did it again and followed the bridge in http://www.ee.unlv.edu/kevin/index_files/labs/320L.pdf (as in the picture at http://www.ietucsi.com/layout/KABOOM.gif , you can clearly see that it is a 12-0-12V transformer. This time I've connected the circuit to both 12V where I connect to the the...
The transformer gives an input of 12Vpp (checked it with an oscilloscope), so the amplitude is 6V per each peak. When the input is rectified (all +ve polarity) won't the value drop by 1.4V since two diodes are forward-biased? Shouldn't the output be around 4.6V, but instead I got a 5.6V output...
The output is is approximately 6V AC (all +ve polarity) after rectified. It is read from the oscilloscope where the probe was connected across the 10k ohm resistor.
I tried the experiment with different apparatus this time where I am using:
1. Step-down transformer (220V to 12V)
2. Four 1N4148 diodes
3. 10k ohm resistor.
It is a bridge connection. Below are pictures of my circuit and its output . The output is 6V (amplitude for a peak) and there are...
I am constructing a full-wave bridge with the following:
- four D1N4148
- Function generator (50Hz with 10 Vpp)
- 1k ohm resistor
- Oscilloscope
I've been trying to construct the circuit, but every time I did it I always get a half-wave instead of a full-wave. All the diodes are working...
I a question:
1. How does voltage regulation works? I was told that if we set the value of the capacitor so that it supplies one-half of the reactive power absorbed by the line we will get a perfect voltage regulation. Anyone knows how to come up with the equation?
I am nearing my second year in Telecommunication and below are my answers:
Question: Is engineering difficult?
1) A definite YES ... unless you are good in Maths and Physics, then you do not have anything to worry about.
Question: What engineering discipline should I study?
2) I rather...
I have an assignment that requires me to discuss why do we step up voltage when transmitting power over long distance.
I was told that in having a high voltage you have a low current, which then reduces the power loss. What I do not understand is how does low current relates to the reduction...
