    rms value of current

    Have you seen the image that I have attached in my post? As I know if the current signal is given than we can find out rms current, peak current and average current. Current signal is represent in image. I have solved for rms current and average current. I did all calculation but when I looked...

    Signal is periodic or aperiodic

    I agree but I am not asking the exact answer. Main problem is that, if question is given for periodic or a periodic signal then I can solve the question ie I did in my first post. I can put the value in formula and can find out the time. I am asking in practical way. DC source that generates DC...

    need help on clock D flip flops table

    OK thank you now I understand. Now I am confused on JK flip flop, check the following condition is true or not, When the both input of jk flip flop is low than output does not change. That means it's store previous value of raising edge When both input of JK flip flop is high than the output...

    How to find out current in circuit?

    Do you mean, the value of R may be anything 2, 4, 8 ohms etc. I have to take one value then I have to find voltage and current through R I did as you said If R= 2 ohms then voltage across 2 ohms resistor is 29 volts
