I was wondering if there are any ways to measure the amps since I don't know where I got the DC motor from and there are no labels? I am trying to find a way to measure the motor's power output.

Hi, I have a dc motor which I am not sure of it's power and was checking the volts and amps. I used a drill to rotate the dc motor. I have a multimeter and I was measuring the motor output, the outcome I got was 40v and when I checked the amps the motor suddenly slows down then stop after...

Now I understand what you mean. Sorry I was thinking about recharging theory. Yes you are right about the constant energy output that the dc motor make. What I have forgotten to tell is that if I recharge the battery or secondary battery or so, so if I use 16.8W and recharge the battery in 2...

If I want to measure the power output for 1 minute. Do I divide 16.8 by 60 = 0.28 joules?

So if I get the dc motors running for 2 hours then it will produce 33.6W? = 16.8 x 2 = 33.6W So how do I work out the watt for minutes and seconds?

I multipled 60 because of 60 minutes in an hour. So you are saying that the energy 16.8W is applied as an hour?

Hello, I have been researching on electrical output and it power and working out how much power I use at home and have been doing a project to make power. I wanted to make sure if this calculation is correct... I use a 12V DC motor with an output of 70mA which creates 0.84 Watt...

Ok, if I make my own circuit to get DC to AC from the motor then will the globe work?

I understand about the normal old globe will work perfectly but what about those new energy efficient globes. I would like to use those since they use a lot less power than the old globes. Old globes are usually 60W to 100W and the energy efficient globes only use aound 10W. So that is why I...

So if I use the DC motors to power up the globe then I need to adjust the correct Hz for the globe? If that is so, how can I adjust the correct Hz?

Thanks Negitron. That is the exactly the answer I needed. One more question, the light globe have Hz. So what is Hz and what it does?

Is it possible to light a globe - a normal energy efficient globe of 10 Watt usually powered by 240v or so. Can the globe be powered if I use 24v and put a lot of amps to power it up? According to the PIE formula (Watt/Current*Volt) thanks

The voltage regulator have 3 legs, 2 for input and one for output to make a constant voltage. I was wondering if this is possible? 2 x input of 12v and can the output be 24v or only under 12v? thanks

Sorry, I should've said that the 2 dc motors combined are driven by mechanical torque and doesn't receive any power but to create power. I wanted to know if there are any ways to get 24v using 2 dc motors or not?

Hello all, I was wondering if it is possible to increase voltage if you combine 2 DC motors together? I know that it is NOT possible to increase the voltage if you put it into a series circuit since it won't work. As for the batteries you can increase the volts if you put them into the...
