    Engineering Calculating R1 for LED Circuit Question with 12V Supply Voltage

    In the circuit the LED's rated current is 20 milliamphers. With a voltage drop across the LED of 1.5 volts, calculate the value of the series resistance R1 necessary to be used if the supply voltage is 12 volts DC. Here is how I answered this, I am not sure if I am right. R1=Er1/Ir1 R1=...

    Calculate Capacitor for 2 KHz Series-Tuned LC Circuit

    This is a home work question. I used the LC formula. If i knew how to scan it and put it on this thread I would. i am taking baby steps here:)

    Calculate Capacitor for 2 KHz Series-Tuned LC Circuit

    What size capacitor would you install in a series-tuned LC circuit with a resonant frequency of 2 KHz the circuit will include a 2 mH inductor? This is my question and here is what I got. Just want to know if it is right. 2.52 i do not know how to put the formula in here. can anyone show me...
