### How to step up voltage on a stompbox or other European device

I have some musical devices brought from Europe that I would like to convert. I'm tired of having those step-up boxes for each device. I'd like to simply convert once and for all. The transformer ...

### Converting 24V AC into 230V AC [duplicate]

In my basement I have 24V AC power outlet. I need it to be 230V. I found some fairly big, old transformer core, on the one side of it I winded 3 turns of standard power cable, on the other side I ...

### Current measurment in energy meter

In AC circuits at the meter we have line and neutral going into the meter and then all devices are connected to it. For each and every device, we require a line and a neutral connection. If I want to ...

### Step-down transformer AC to DC voltage conversion problem?

I got a step down transformer from an old black and white CRT TV that is about 18v 0 18v, 10A AC current output. I wanted to convert AC to DC, so used four 1N4007 diodes as a bridge rectifier. When I ...

### Does combining two separate transformers double the voltage?

Can I wire the outputs of two separate transformers to get twice the voltage? I have two separate, identical transformers from neon signs. Both put out 6000 volts at 30 mA. I would like to use 12000 ...

### Getting the right converter for this 110/120v device, where the power is 220/240v

I have an appliance designed for 110/120v. It says it runs peak at 1200 watts, but I can't find yet any mention of Amps. I'll be using it in Europe at 220/240v, if it is possible. I understand I can ...

### At very high frequency (700 kHz), an AC circuit has a voltage reading 10 times the EMF, why is this?

I've set up an experiment in which I vary the frequency of an electric signal using a waveform generator. The experiment is testing a transformer, but I've encountered a problem on the primary circuit ...

### Can I use more diodes to reduce the voltage off a diode bridge?

I have a transformer labeled as providing 9Vac, 3.36 A. It appears to provide 9.4 v ac according to my multimeter. It runs through a diode bridge (WAB 040 diodes -- already fried the last version), ...

### Multi-tap transformer current handling capability

I have a transformer with a single secondary winding but with multiple taps, as shown in the image. It is rated at 4A @ 24V (96VA). Does this mean that at lower voltages (16V and 8V) it will be able ...
