    Adding resistor and capacitor in parallel

    Thanks rl.bhat. I am wondering though how did you get 12j for the numerator? I'm sure it relates to 4 x 3j = 12j somehow but I'm not sure why...

    Adding resistor and capacitor in parallel

    Hi all, I am meant to find the total impedance across the circuit but am having trouble with one section of the circuit. This section comprises of 2 resistors and 1 capacitor in parallel. The two resistors are 8 ohms each and the capacitor is 3 ohms. So the process is meant to be: Z = (...

    Solving Logarithms: Finding the Solution for ln(x) + ln(y) = 0

    Thanks for the replies everyone. I had already considered ln(x) + ln(y) = ln(xy) but I don't know how to approach the problem using this law. Any directions? Thanks again.

    Solving Logarithms: Finding the Solution for ln(x) + ln(y) = 0

    Hi everyone. I know this question is quite simple but I can't wrap my head around it at the moment.. Solve for y: ln(x) + ln(y) = 0 I've tried differentiating both terms and then arranging for y but I get y = -x. The answer is meant to be y = 1/x. Thanks all!
