Alright, so I THINK I know what they do, but I am not quite sure.

As far as I'm concerned, a half-wave rectifier only creates an output voltage half of the time, which basically makes the ouput voltage look like a sinusoidal waveform, with the negative end cut off.

Similarly, the full-wave rectifier converts the positive and negative ends of the AC waveform into output voltages, which basically would make the output voltage look like a sinusoidal wave with the negative half flipped upward with respect to the x-axis making it look like a series of identical bumps.

Is this correct? If not can someone further explain to me how they work?

My microwave is metal inside, and has/came with a metal revolving tray. It's definately a microwave, and it's definately metal inside.

I was under the impression that metal shouldn't be put inside a microwave oven.

It's a sharp, jet convection and double grill 800w band D microwave.

For a school project I must make a container out of paper, but can use any material on the inside, and I need to make the egg survive a 13 foot drop.

I can't figure it out, and I'm allowed to use the internet to find out.

thanks,

This is a general question to anyone who works in or employ's people in the electrical / mechanical repair industry within the UK.

We are a small independant electrical mechanical engineering company that specialises in the repair of power transmission products, pumps, motors, gearboxes etc and also carry out mechanical repairs in our in-house mahcine shop.

I am trying to get an overall view of what the average hourly labour charge is for these services. This is totally anonymous but if anyone does reply could they indicate the size / spec / location of their company.

We currently charge between 37 and 44 pounds per hour for our services.

Please be honest.
