ELECTRICAL CIRCUIT ANALYSIS Lecture Notes
The phasor diagram represents the phasor (or vector) relation of the three phase-ground voltages (for simplicity, in a balanced system). The diagram is based on counter- clockwise rotation. In a three phase system the voltage or current sinusoid attain peak values periodically one after nother.The sinusoids are displaced 120 degrees from each ...

LCR Circuit
Phasor diagram of current Vs voltage for resistor, inductor and capacitor for RLC series circuit. The current will equal all three as it is a series LCR circuit. Therefore, If X L < X c, then tan θ < 0 and the voltage lags the current and the circuit is said to be capacitive. If X L = X c, then tan θ = 0 and the voltage is in phase with the ...

Time Constant: What it is & How to Find it in an RLC Circuit
This term is known as the time constant. So time constant is the duration in seconds during which the current through a capacities circuit becomes 36.7 percent of its initial value. This is numerically equal to the product of resistance and capacitance value of the circuit. The time constant is normally denoted by τ (tau).

72.63 -- LRC circuit: phase differences, resonance
Since XL < XC, the phase angle for the current in the circuit is negative. If we increase the frequency above the resonant frequency, XL (= ω L) increases and XC (= 1/ω C) decreases. At 503 kHz, XL is about 9.48 kΩ, and XC is about 1.44 kΩ. The impedance of both together is about 9.37 kΩ (√ ( XL2 - XC2) ≈ 9.37 kΩ).

Gantt Chart vs. PERT Chart vs. Network Diagram: What's
Gantt Chart vs. PERT. Both Gantt charts and PERT charts are visual tools that help organize tasks when building a project schedule. The obvious difference is that a PERT is a network diagram, while a Gantt is a bar chart. PERT charts are great in that they clearly show you when a task is dependent. That is, if one task can't start or end ...

Experiment 2: Oscillation and Damping in the LRC Circuit
The decay time of the LRC series circuit is the time when the exponential factor has become 1/e, i.e., when the exponent is minus one. Thus, the decay time, tD, is: tD 2 (19) We will now show that for cases where the decay is not too rapid, or more specifically, when several oscillations occur in a decay time, the difference between the damped ...
