By connecting collector to base, you get a *lower* forward voltage drop than with a simple diode.
Example: germanium diode-connected transistor has a drop of about 0.13 volts, rectifier diode about 0.3 (over 2.5 times)
It's just that rectifiers are optimised for rectification, are designed to work at (generally) higher currents, and are cheaper.
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
the usual semiconductor rectifier used in the microwave band is a gunn diode. Vacuum tube diodes are sometimes used too.
A 1n4007 is a diode and not a transistor, the 4007 don't really represent anything, the 1n4007 is a axial lead standard recovery rectifier, working peak reverse voltage = 1000V, the forward current for this device = 1 Amp. More data about it can be find in the data sheet.
The metalloids is combined in transistor radios to make them of high quality.
there are two diodes there but to use them as rectifiers never
The twoends of a center tap transformer cannot be used without a rectifier.
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
because we can get two different value at outpit.if we cosider tree point at secondery side of rectifier of 100volt that is A,B and C than we can get 50 vol bitween A and C.and we can get 100 volt bitween A and B.so no need to use two different value rectifier of 50 and 100 valt
Yes, if the transformer output is center-tapped; otherwise, no, a bridge rectifier requires four diodes, or six for three phase power. More technically correct, what we are talking about is a full-wave rectifier. A bridge rectifier is properly always four or six diodes.
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
No, a transistor does not change alternating current into direct current. A transistor can amplify or switch electrical signals, but it does not convert between AC and DC. Rectifiers are typically used for converting AC to DC.
No, a Transistor operates with a modulated direct current. You need 4 Diodes to manufacture a rectifier to deliver direct current at the outlet, with alternating current at the input. A Diode is effectively a one way valve to address one halve of the cycle of the alternating current.
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
yes, diode can be used as rectifier diode to convert ac to dc
