    Need some coaching,not sure where to start (KVL)

    The usual way to apply KVL is by using mesh currents; however, since branch currents have already been identified then one can use those instead. KVL states that the sum of voltage drops around a loop equals zero. There are two loops here so there must be two loop equations: {clockwise}...

    D-Type Flip-Flop (74HC74)

    So you are using a dual D-FF as a single SR-FF, but the SR inputs are active low. You could use cross-coupled NOR gates to get a SR-FF with active high inputs. But any SR-FF will be in an unstable state when both SR inputs are activated. How will you insure that the reed switch input has...

    Need Help Finding the Output Frequencies for Two 4-Bit Binary Counters

    It appears to me that the circuit has four separate counter sections wired in series in the following order: ÷4,÷2,÷6,÷2 for a total ÷96. Have not done much work to verify correctness, but that is my first impression.

    Ideas for a school experiment?

    Every high-school physics lab seems to have a Tesla Coil. But how many have a solar-powered Tesla Coil? OK, you probably don't have enough time to build the whole device; however, what about looking at just one aspect of the problem of miniaturizing the device for solar power? Such as...

    Finding cutoff frequency with Short/Open Circuit Time Constant

    The symbolic algebra engine I use is MathCad 15 running in a Windows 7 virtual machine on my CentOS 7 Linux computer. Have just installed the Linux version of Maple 2015 and am trying to learn how to use that.

    Question on using op amp applications

    It is not really necessary to calculate with time functions, the voltage can be found simply from radian position as shown below:

    Finding cutoff frequency with Short/Open Circuit Time Constant

    I tried making a Bode plot of the circuit the old-fashioned way. Just what points on that graph do you think you are calculating?

    Get analytically circuit output voltage

    Suppose the question were not to find the value of Vout, but rather what value of AC voltage across R2 would make the half-wave voltage at the voltmeter read as 5 volts? This is not a circuit analysis problem but a question of what do voltmeters actually measure.

    Uses of inductors

    A few common uses come to mind. Inductors are used to design passive filters for a wide range of frequencies. They are used in RF circuits to block high frequency signals while passing DC biasing current. They are used in voltage regulators where the inductive voltage 'kick' is used to boost...

    leading or lagging of voltage?

    I don't dispute your description; however, it is not a very useful concept for doing circuit analysis where we like to pretend that current flows through the capacitor.

    leading or lagging of voltage?

    I don't believe I've ever seen the topic of "capacitor accumulation/depletion current" discussed in any circuit theory textbook. Do you have a reference where it is explained?

    leading or lagging of voltage?

    The concept of leading or lagging voltage arises from frequency domain analysis at some steady-state frequency where the phase angle is meaningful. So it is more appropriate to use the concept of phasors rather than using differential equations to explain signal phase. Consider the following...

    Capacitors dielectric

    So does that mean we can analyze a capacitor circuit with KVL and have the loop currents 'appear' to flow through the capacitor components?

    Capacitors dielectric

    Why would that be a useful concept for applying Kirchoff's Current Law in a circuit with a capacitor? If current is flowing into one side of a capacitor and an equal current is flowing out the other side of the capacitor, then can't we just pretend that current is flowing through the capacitor...

    voltage drop help

    Would a single resistor be a simple enough circuit? The resistance value would depend on the current needed to drive the LED.

    The Formula for the Equivalent Resistance of Complex Resistance Network(Circuits)

    Here is an alternate procedure of solving for the lattice resistance using KCL with node equations. Not sure which method should be regarded as the most magical.

    Creating a latch circuit with logic gates

    The point was that the data is not clocking through, rather it is gating a counter. To make a JK-FF behave like a D-FF (where the data does clock through) it would be necessary to connect one of the JK inputs to the pushbutton and the other kept at logic LO.

    Creating a latch circuit with logic gates

    Noticed that the gate diagram shows the JK inputs of each FF are connected together, so when the JK is HI the FF will toggle the Q outputs on the negative clock transition, and when the JK is LO the Q outputs will remain unchanged. Also, each triad of FF's is connected as a 3-bit binary ripple...
