4 bit Down Counter Asynchronous type in tamil

Asynchronous Type Down Counter
counter
Counters are used to count the clock pulses. The clock pulses occur at regular intervals. They are used to measure the  time and frequency. We can also say that counters are sequential circuits which change their pre-defined states with the help of clock pulses. They are constructed with flip flops and logic gates.

They are of two types
1.Asynchronous counter
2.Synchronous counter

In the asynchronous counter, an external clock pulse is provided for only the first flip flop, thereafter the output of the 1st FF acts as a clock pulse for the second FF and so on. In the case of synchronous FFs, all the flip flops are triggered simultaneously by an external clock pulse.

Sir exams ku important Questions kudunga sir

[mahasmrti]

Hiii, sir
One small doubt , my questions is.
One DC Supply circut equipment it is connected in each battery 12V 100AHC X 04 battery serious.
(Just like it is charger in mean FCBC - Float cum booster charger)
Battery connect in serious total in circuit 48 V 100 AHC
And it equipment load connected(DC equipment)in 48V DC, 2.2 Amps DC.
So,
My question in the backup time of the that equipment. In 2.2 Amps Load DC

Pls solve and published one video sir,

Sir plse post video for K maps plse ! 4 variable 5 variable 6 variable plse

Sir I have a doubt 😢
In my college they teach that resistance will resist the flow of electron and it is also in the text book and google

But how it resist the voltage can you explain please or if you can make a vedio please make

Many people have doubt about it
