Respected sir how much current it can give???...plzzz tell

You just showed the potential difference not the current...you did not switch your multimeter into current....currents pertain to ampere
Current measure kare tab bataye

haha , calaculated voltage only. not the current, but ur title is increase output dc current.

Can I use 2n2222 instead of that transistor
miha peterle (3 months ago)
this is not good regulator because 2n 3055 base is driven by curent and 7812 regulator give us 12v not 11.88 but u need voltage on the input Vout + 1.75V so in these case yours positive voltage regulatore need 13.75V on the input to work appropiately you got 12Von your outpu just because 1V was voltage drop on the transistor and your regulator just decipate 1V * 200mV for led its 0.2W of heat trought transistor if you woul input 20V jou will get about 18V on the input

miha peterle you seem to know a lot about electricity/electronic circuits. Could I bother to ask you a few questions about electrical amplification using transistors? I’m really lost. If you want to help please let me Know at your earliest convenience and I will jot the questions down. If you don’t know the answers, it’s fine, I’m just looking for some guidance. Thanks in advance for any help you may provide, Ray

Hey stupid chutya...do you even know what is Current and voltage?...waste of time.

Wrong connections.

The use of this circuit is to increase the current gain while keeping the voltage at 12v DC. Lm7812 cannot alone withstand large amount of current. Transistor is working as common collector amplifier which has voltage gain of 1 (less than 1 in practise).so the output must be around 0.7v less than 12v due to drop across b-e junction of transistor, with current gain of around 20 to 70 for 2n3055.This circuit will increase the current carrying capacity of regulator.

i agree with

Finally u dont check the current

sorry, I will check on next video

Could have used an n channel mosfet as a low side switch instead of the 2n3055 and used your regulator to power the gate. That way the regulator won't have to dissipate nearly the same power as your design

Your input current 13 something and your output 13 approx.. Lol your current is decrease..
POWER GEN (5 months ago)
The LM type regulator has a maximum of 1.5A but The 2N3055 is a silicon NPN power transistor of 15A so one of the current quality managing circuits

Good video. For more stable output voltage, it's better to apply 7812, 3.3 ohms resistor and MJ2955. Greetings from Indonesia

Can i use 2n3055 transistor for 24 v circuit ??
Deepak Nanda (6 months ago)
Transistor can increase voltage alone..like this circuit..it only act as a regulator switch..

Yes, you can use it

what if i want to amplify......the current 5v current .. can I use 7805 from 12v to amplify the current

Hazim Safawi all the best for your exam. But just know, I try working on with this circuit by using Proteus Software. And yes, the value voltage from 5V to decrease to 3.5V . But I didn't measure current value. Hopefully it will increase.

ZAIDATUL AKMAL not yet. Right now I'm paying my attention for my exams. ☹
ZAIDATUL AKMAL (8 months ago)
hi Hazim Safawi, have you done this circuit?Is it working or not? because i also need to increase the current value for charging the mobile phone
Zim Unknown (8 months ago)
debarghya m i didn't know that before. Thanks for the information!
debarghya m (8 months ago)
Hazim Safawi no...it won't....it cannot increase the current.... current will still be 250mA.. what you can do is use 7805 voltage regulator with 2N3055 or similar transistor... You will get about 5v 250mA.
