Yes you could. in a full bridge rectification circuit we typically represent 1. Mains Voltage AC (in Australia is 240 V AC) 2. We then show the STEP DOWN process via a Step Down Transformer from Primary side to Secondary Side let's say for arguments sake, we stepped down from 240 V AC to .. oh.. let's use 20 V AC for sake of demonstration 3. then of course we now feed this 20 V AC into a Full Bridge Rectifier to get Pulsating DC 4. We then Smooth the Pulsating DC out by using a capacitor (and this only gets us an approximate voltage) 5. then to get a bit more accurate we use a voltage regulator to obtain the (let's say ) Required 5 V DC Now.. your question is .. Why use the Tranformer why not just throw in a VOLTAGE Symbol and set it to 20 V AC well. yeah.. you can do that as well but i suppose he demonstrated it this way because 1. it's traditional to show it this way 2. if he didn't, someone would be saying "what the fuck dude, where is the step down transformer" LOL so.. there is also that
@@nirajsahu8789 AC and DC supply looks the same in LTSpice models..If its AC, the text (sine...) will be written. In this case, the supply is indeed AC and we rectify it to DC
What's the purpose of using the transformer? we could connect 5v ac to the rectifier circuit without a transformer, right?

If vmax is 5v. How come after adding large value of capacitor it is still 5v dc. Shouldn't it be 0.637*5.
thank you sir
Thank you sir
thank you sir
THANK YOU SIR
why we use inductor as a transformer?
Because there is not direct transformer model available in the LT spice..
@@Chitranshleo thanks
@@Chitranshleo he already gave 5 volts as the supply, so transformer is not technically required
@@aneeshprasobhan supply is dc
And we need ac .
