Electrodynamometer
Electrodynamometer is a device that we can use for measuring volts, current, and power. But mostly this used for measuring power in the circuit. For the construction of electrodynamometer wattmeter we gonna need some important part for this stuff to work.

So I've recently purchased an ionizer from Walmart... going to withhold the name for now.
Since I started using it I've experienced many strange electrical phenomena. I've done a ton of troubleshooting, and narrowed it down to the device itself. I was tempted to try a different wall wart, but...
Hi All,
I'm new here. I searched for existing answers to this question but did not find an answer.
I was doing some sound-proofing DIY in a one room at home and pulled-in some cable to replace old 1960's cable.
Now that I've sealed all the walls and floor and turned my attention to wiring in the...
I have noted more and more items ask for a type A RCD rather than type AC, with electric car charging units it is often even better than type A required, but with car charging units it is hard wired so clearly should be part of the inspection and looking up one make of charger unit not really a...
It might be easier to list the few things right with it. I have noted what appears to be burnt or frayed hot wires. I have only seen the pictures provided but this looks less than professional to me. The house is 1957 construction and may have aluminum wiring (probable cause for the burnt...
Can anyone tell me the Legal distance a induction Hob has to be installed from a sink please, my housing association say they are going to install one 12 inches from my sink and I said this is wrong, also it is to be installed under my window which I have to lean over the hob to open the window...
At my father in laws house, for the last 5 years two of the bedrooms lights haven’t worked. The bedrooms that the lights don’t work all seem to wired correctly.
apart the landing, which does work. But appears to be wired incorrectly?
rather than having a live in, 3 red loops, and black line...
Hello all,
I recently redecorated my living room which meant stripping off the wallpaper. While doing so, some moisture got into the living room light switch (it's a 2-way). I took off the switch plate to dry it out but noticed a wire seemed to be unconnected. I'm assuming this black wire...
I hope someone can help. I should have taken a picture of the old fitting but as it was 3 wires I thought it'd be okay. In the picture you can see I have the black and blue together, the connections marked 'loop' are empty, red and brown are together and earth goes to the rose.
My problem is...
Oven element broke in half and started sparking even when all controls were turned off. Resident manually switched range breaker off. I replaced the element with oem replacement. I made sure all wiring was secure and the element connections are not making contact with the back cover panel.Now I...
So I moved in to a brand new duplex and the fan in the main bedroom seems to buzz and only seems to buzz of a night time or after the fans on for a little bit.
But also can go all day with out buzzing and bam as soon as were in bed buzzes and it's all random buzzing or humming something like...
I've lived in this house for the past 8 years, never had a problem. until a few months ago the lights in the living room, oven, fridge and central air all started to stop working sporadically. checked the breakers and they don't get thrown. noticed that the light is actually getting enough power...
Going to see a new customer tomorrow. He thinks his new smart meter is reading higher than he thinks.
I don’t know the house, but guessing at still old fuseboard rather than mcb or rcd looking at the street address.
Anything easy I should be looking for to explain high usage?
I’ll suggest LED...
Long story short i had a friend helping me out with some DIY today and I have realised that he left the wiring like pictured. I have and voltage tester so i have worked out that the middle red wire is the live one.
Long story short they are now not working (i have tried some variations based...

This is really pi$$ing me off now.
Got an 03 combo van. Stock radio would light up but screen was smashed and couldn't get it to play anything.
Bought an aftermarket radio. Swapped them over without a problem, or so I thought.
It worked fine, until the van started moving then it would cut out...
Hi,
Can anyone please explain why my friend's 30mA trip RCBOs passes the trip test (e.g. x5 is less than 40ms) when the test is done at the consumer unit but fails when the test is done at the sockets.
Is he doing something wrong or is there a fault somewhere (the RCBO or the circuit...
Hi all,
I am hoping you can provide me with some insight. I've just bought a new light fitting, and before fitting I attempted to turn the downstairs lights off at the CU. It killed all lights bar the kitchen light (the one I was planning to change ). However, to stop power to the the kitchen...
Hi everyone,
I've recently done some testing on some welfare trailers used on building sites on behalf of the rental company at their base. Mixture of fixed wire/PAT/FAT to make sure they're going out to the customer OK.
I've done 8 so far and they were brought brand new 12 months ago and I've...
So, went to look at a property for a landlord. In the bathroom there is an electric shower in zone1, but it's mounted approx 2 foot above the water line. The isolator pull switch is outside zone2. Oh and the circuit is rcd protected and on a separate 45a breaker.
My thoughts were....why would...
