    What is the function of this 6 volt timer and motor control circuit?

    I have found this circuit and I was wondering what it did. Does it control how long a motor is running?https://www.google.com/search?q=6+volt+timer+55+motor+control+circuit&safe=strict&biw=1607&bih=834&source=lnms&tbm=isch&sa=X&ved=0CAcQ_AUoAmoVChMI28KE9-KkyAIVkKWICh2bxQ23#imgrc=TVAXCdSBnuQRPM%3A

    Circuit that controls time and distance for a 7.6v vehicle?

    I found this circuit. Anyone know if it can control the duration for the current to flow? I am going to be using about 7.6 volts but this circuit is rated for 12 volts. Will it still work...

    Circuit that controls time and distance for a 7.6v vehicle?

    I have to design a circuit that can control how long it takes for it to travel a given distance. I do not have much progress. I am wondering what type of circuit this is?

    Do capacitors block unwanted ac frequencies in the wires?

    Right. This is a strange question: When capacitors are connected in series they have low impedance at only certain frequencies. Many frequencies yield high impedance. Can a high impedance AC frequency charge a capacitor? Do capacitors filter frequencies in wires parallel to those capacitors?

    Do capacitors block unwanted ac frequencies in the wires?

    this is not HW questions. These are questions that will give me a more solid understanding of capacitors and inductors when answered.

    Do capacitors block unwanted ac frequencies in the wires?

    well your circuits are low pass and high pass filters because impedance of the components change at different frequencies. What happens when you connect a dc battery to a capacitor? will the capacitor charge and then discharge after the capacitor voltage=battery voltage.?

    Do capacitors block unwanted ac frequencies in the wires?

    I have been studying capacitors and inductors recently and I have seen this video. I have a few questions about capacitors and inductors. Capacitors: 1.how do capacitors discharge? 2. What happens when you apply direct current through a capacitor? 3.Do capacitors only allow certain...

    Calculators Can TI-84 calculator send text messages or email?

    Well the texas instruments ti-84 calculator is my favorite toy. I use it for anything I can from getting a girl to put her phone number in my calculator to programming. Is there a way to somehow add an external circuit that can make the ti-84 send text messages. I bet there would have to be a...
