Full Wave Bridge Rectifiers

in this video we're going to discuss the full wave bridge rectifier circuit so on the left side we are going to apply an ac signal that is an alternating current signal to a transformer now to the right of this transformer we have four diodes connected like this and the way these four diodes are connected will allow us to convert an ac signal into a dc signal which is the main purpose of a rectifier so this is going to be the output of the bridge wave rectifier now let's put a resistor here let's call it resistor r now we have four points of interest so let's call this point a point b point c and point d and this is going to be d one or diode one diode 2 diode 3 and then diode 4 on the upper left side and so this is the basic picture of the full wave bridge rectifier circuit this is how it looks like now let's talk about the operation of this circuit and so here is an ac sine wave and during the positive half cycle of this wave the top part of the right side of the transformer is going to have a positive potential and the left side will have a negative potential
