Chopper – Definition and Working Principle What is a Chopper? A chopper is a static device that converts fixed DC input voltage to a variable DC output voltage. It is basically a high speed ON/OFF semiconductor switch. It may be thought of as DC equivalent of an AC transformer since they behave in an identical manner. Chopper is fed through a constant DC voltage source and its output is variable DC voltage. The average value of output DC voltage may be less than or higher than the input DC voltage source. A simple diagram defining the chopper is shown below. A chopper is a DC equivalent to an AC transformer having continuously variable turn ratio. Like a transformer, a it can be used to step-up or step-down the fixed DC input voltage. On this basis, there are two types of chopper: Step-up and Step-down Chopper. A chopper whose average value of DC output voltage is more than the fixed DC input voltage is called Step-up Chopper. While, a chopper whose a...
Top 10 Termux command 1) - cp - v ; used to prints informative massage 2) - cp -r ; used to copy any directory 3) - mv -u ; update-move when source is newer than destination 4) - mv -v ; to move any directory 5) - ls - n ; to display UID and GID directory 6) - ls --version ; to check the version of ls command 7) - cd -- ; show last working directory from where we moved 8) - ls -l ; show file action like - modified, date and time, owner of file, permissions Etc. 9) - ls help ; show display how to use "ls" command 10) - cp -n ; no file overwrite
Using Ping in windows command line a. open command prompt (cmd) in windows (press win+R and type cmd) b. Type " ping target " (replace target with IP or website or target). For ex: ping www.xyz.abc or ping 127.0.0.1 c. Packets will be transferred between attacker and target. 0% loss indicates ping command completed and packet are successfully transferred . d. TTL stands for Time to live and generally 4 packets are transferred between attacker and target but it can be increased. e. To understand more about ping command, type ping -h or ping /? In internal. It will open help for ping command. It can be used in kali Linux as well.
