A: Actually there is no changing of diodes required to get negative voltage out put the two cathode to ground if you have a load the voltage across will be negative. Electrons only flow in one direction where the measurement point are located across the load makes positive or negative.

What does the out put wave form looks in a rectifier?
A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.
What is full wave bridge rectifier?
A: This type of rectifier circuit will conduct current trough a load both times during the AC positive and negative cycle
When electrons are moving from negative pole to positive pole in the circuit then current in the circuit will be moving in which direction?
always current flow from the opposite direction of electron
What is the direction of an electric current in a circuit?
every electronic circuit works on the principle of direct current .hence from negative to positive.
What is full wave bridge rectification?
This type of rectifier circuit will conduct current trough a load both times during the AC positive and negative cycle
Which direction do you put arrows in the circuit diagrams?
We will put the arrows in the circuit diagram from negative terminal to the positive terminal🤗🤗 Thanks..................
Does electricity travel from positive to negative or negative to positive in a circuit?
It goes negative to positive.
What is the difference between a one diode rectifier and a two diode rectifier?
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
Can a rectifier work either way?
if you are looking for the direction of rectifier than Yes. the rectifier convert the alternating current to one directional Direct current. It work as short circuit on the case of forward biasing and work as open circuit on the reverse biasing so it can work only in one direction.
How does a rectifier work?
In a simple half-wave rectifier, during the positive part of the alternating wave the diode conducts, making the load voltage equal to the supply voltage. During the negative part of the alternating wave he diode blocks, making the load voltage zero.Another explanationFor as long as its circuit is alive, any sine wave signal running at a certain frequency has the positive part of its wave immediately followed by the negative part of its wave immediately followed by another positive part of its wave, and so on.A half-wave rectifier would basically eliminate the negative part so the output of the rectifier, as seen by the load that is connected to it, would receive a positive half wave voltage then a zero voltage during the negative half cycle of the waveform, then a positive half cycle again, and so forth.A full wave rectifier does the same thing for the positive half of the cycle and then basically flips the negative part of the waveform to give the same output as the positive part, so you have a series of positive pulses. The signal, as seen by the load after the rectifier, never goes negative.
What is the direction of conventional current in an external circuit?
The conventional direction of current flow in a DC circuit is from positive to negative. In reality the electron flow is from negative to positive. Most electronic schematics today still use the conventional current flow when drawn.
What is the polarity of a circuit?
The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.
