used in these applications is usually an electrolytic type with a very large capacitance value‚ typically ≥1000μF. We will first look at the case of the half-wave rectified circuit‚ initially with no load resistor attached. For simplicity‚ the transformer has been replaced with a low voltage a.c. source. The resulting oscilloscope graph for this circuit is as follows: From the graph you can see that the output voltage shown in red holds its value at the maximum voltage‚ once the charge

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic
