A:
Name different types of rectifier.
Rectifiers are electrical devices which contain one or more diodes to allow the flow of current only in one direction. Rectifiers are classified based on type of supply, components used, bridge configuration and control nature.

- You are working in a factory that produces long bars of copper with a square cross section. In one section of the production process, the bars must slide down a plane inclined at an angle θ = 21.0° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown, separated by a distance ℓ = 2.00 m. The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.00 Ω is connected between the upper ends of the rails. Determine the magnetic field necessary in your device so that the bars will arrive at the bottom of the plane with a…My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time.
