Want this question answered?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
A full wave bridge rectifier converts AC (Alternating Current) into DC (Direct Current) with an AC component. To achieve DC only, the output of the bridge rectifier must have the AC component removed by bypassing it, usually with capacitors. It consists of 4 diodes in a bridge format. During one half of an AC cycle, two of the diodes conduct and on the other half a cycle the other two conduct. Diodes allow current to flow in one direction only.

A balanced bridge has zero volts across the two test nodes, while an unbalanced bridge has non zero volts.
Because two diodes is not a transistor. There is an interaction between the junctions in the transistor, because of their proximity, that you don't get in the two diodes. The only use of modeling a transistor as two diodes back to back is to test a transistor with a multimeter as a quick go-nogo test for basic operability.
Its no longer a rectifier and the resistors may catch fire.
two diodes are used. when one diodes swithes off, the other takes over and hence provides a continuious wave from. thier circuit arrangment is also called half bridge.
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier *********************************************************** A two-diode rectifier is not always a centre-tap rectifier. If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage. (But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)
As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.
A full-wave rectifier (sometimes called a "bridge" rectifier) produces output current on both half-cycles of the input AC waveform. ******************************************** There are two types of full wave rectifier circuit. One uses four diodes in a "bridge"configuration and is fed from a simple transformer winding. The other uses two diodes and needs to be fed from a centre tapped transformer winding.
Four diode rectifier not require a center tapped transformer.

A rectifier is at least two diodes, one anode is connected to the other diode's cathode. ANSWER: Any single diode can be a rectifier without being double or quadruple

There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
A transistor is made up of two diodes back-to-back. In a common base circuit - the load is shared between two diodes
