    Simple maths resistance exercice

    This time i got 16 volt could ypu check what i did wrong there are 3 pictures but i write big Watch from the last photo to the first photo https://ibb.co/hZqCAe https://ibb.co/jLETiz https://ibb.co/kPkeqe

    Simple maths resistance exercice

    The thing is RT=R1+R2+R3 IT=I1+I2+I3 and then ohms law.i dont have any current in the exercise.So how am i supposed to do it.if i calculate all the series ohms it makes 37 ohm if i then calculate the pararel resistors ohms it makes 5.22ohm a total of 42.22ohm. I take the total voltage divided by...

    Simple maths resistance exercice

    https://ibb.co/irx3yz Only the example exercise at the end of the picture.I only know ohms law and that P=VxI How am i supposed to do it

    How does a decade counter IC 4017 works?

    Then how are you supposed to control the pulses?What do i need to put in the clock input to control the pulses. For example i saw flashing leds in a order how are you supposed to make it.

    Explanation of a circuit

    Still it is a circuit i got in a class.If it doesnt work :/ Do you think you could just make a general explanation?

    How does a decade counter IC 4017 works?

    Like the title how it works? Only thing i understood is that it give an output based on pulses? What is a pulse? how are you supposed to send specific pulses? I need a more general explanation on IC. Only thing i understood is that NAND AND OR Gates and some basic others. I understood the thing...

    Explanation of a circuit

    Need to understand simply because im pretty slow at understanding things. First what does the 7805 do regulate voltage what it means more exactly? UM66 how does it generate a melody does it make different tones or only one thing. I know transistors boost current and act like amplifiers all that...

    12v 100 ma project check

    The objective of this project is to get a stabilised output voltage of 12v and a current of 100mA. As Mauritius have a 230v AC voltage distribution with a frequency of 50Hz. The VN30.15/10525 transformer fit with a frequency range of 50hz to 60hz and a 230v input.With a 15v Output.The 2,3...

    Beginner regulated power supply circuit help

    Yes thanks i had the info about the 10ms but i didnt understand how it was found.I am using a full wave rectifier it is a project so i need to use a zener diode already found one with reference.I need to explain everything so what about the ripple voltage

    Beginner regulated power supply circuit help

    Hello so im pretty new in electronics and i need to make a regulated 100mA 12v output power supply. The capacitor formula is = Capacitor=(load current*ripple voltage time of one cycle)/peak to peak ripple voltage The zener diode use 20mA so the load current is 120mA. But how do i know the ripple...

    Step down transformer reference list?

    Which means the transformer tolerate additional 10 volts?

    Step down transformer reference list?

    I need to make it on paper before being able to test how can i predict the output voltage of the transformer if it is a 230v one?

    Step down transformer reference list?

    For example i checked the VN30.15/10525 but it has a 230v input while in need a 240v input.

    Step down transformer reference list?

    I know i need 2 or 3 volt higher i just said 20 like this because i do not even know if 15 volt transformers exist I am looking for a decent list or website where i can easily find components i need. But a 240 volt ac to a 12 volt ac transformer is enough to give 12v dc output?

    Step down transformer reference list?

    Hello i am a very big beginner in electronics and i have a project to make a stabilised DC of 12v with 100 mA I need help with the transformer because im looking for one everywhere and i can only find 240v to 110v or 240v to 12v i would like one that would turn 240v ac to 20v ac where can i find...
