NDSU ECE 211 Lecture 20
An inductor’s voltage is proportional to the rate of change of current, making its behavior the current-voltage counterpart of a capacitor.
NDSU ECE 211 Lecture 19
A 2 μF capacitor charged to 12 V stores 1.44 × 10⁻⁴ J, while its network equivalents depend on series or parallel arrangement.
NDSU ECE 211 Lecture 18
A capacitor stores energy, with current set by capacitance and the rate of change of voltage.
NDSU ECE 211 Lecture 16
Finite gain and real-world op-amp limits explain when ideal assumptions work and how practical behavior affects circuits.
NDSU ECE 211 Lecture 17
Positive feedback gives a comparator two switching thresholds, creating Schmitt-trigger hysteresis that reduces noise sensitivity.
NDSU ECE 211 Lecture 15
Op-amp buffering enables reliable cascaded circuit stages, unlike unbuffered resistor dividers that load one another.
NDSU ECE 211 Lecture 14
Ideal op-amp rules yield practical formulas for inverting, non-inverting, buffering, and summing circuits.
NDSU ECE 211 Online Lab 5
Configure the three-in-one meter to measure DC levels and compare a 1.25 kHz sine wave across a resistor divider.
NDSU ECE 211 Lecture 13
Thevenin and Norton equivalents simplify resistor-source networks, and maximum power transfer occurs when the load matches the source resistance.
NDSU ECE 211 Lecture 12
Superposition separates independent-source contributions, while source transformations simplify equivalent practical circuits.
NDSU ECE 211 Lecture 21
Series inductors add, parallel inductors combine reciprocally, and an op-amp with a feedback capacitor performs scaled, inverted integration.
