Note that voltage across a resistor is always in phase with the current through it. In the case of a pure inductor or capacitor there is a 90° (π/2) phase shift between the voltage and the current. In the case of the inductor, the current LAGS the voltage, whereas in the capacitor...
We don’t say “transferred” because, in general, the final state or location of the energy is not important. For example, if the voltage across a resistor is 5 V and the current through the resistor is 0.5 A, the resistor is transferring 2.5 W of power (as heat) to the surroundin...
To reduce the technical complexity of a circuit for measuring the voltage drop across a variable resistor (13) located in an alternating-current circuit, the alternating-current circuit (11, 12, 14, 15, 16) is completed by a direct-current circuit (20, 19, 18, 17, 22, 23) and the ...

CarlNelson, inAnalog Circuit Design, 2013 Output Ripple Voltage Output rippleon a tapped-inductor converter is higher than a simple buck converter because a square wave of current is superimposed on the normal triangular current fed to the output. Peak-to-peak ripple current delivered to the outp...
A resistor-ladder voltage generator circuit is provided, which controls so that k switches among consecutive (k+1) switches out of a plurality of switches connected to the resistor ladder circuit are
A resistor-ladder voltage generator circuit is provided, which controls so that k switches among consecutive (k+1) switches out of a plurality of switches connected to the resistor ladder circuit are simultaneously set to an ON state, and which temporally switches the value of k. This allows ...
To accurately measure device current, another VCA824 amplifier was used to differentially measure the (Kelvin- connected) voltage across a current-sense resistor, Rcs, between the FET source and ground. Using a wide-body 6432, low-inductance (<200 pH) resistor with a value of 0.100 W ...
