WebThese equations show that a series RC circuit has a time constant, usually denoted τ = RC being the time it takes the voltage across the component to either rise (across the capacitor) or fall (across the resistor) to within 1 e of its final value. That is, τ is the time it takes VC to reach V(1 − 1 e) and VR to reach V( 1 e) . WebAug 2, 2024 · Φ is the phase angle in degrees. The larger the phase angle, the greater the reactive power. Cos (Φ) = P/S = W/VA = power factor, p.f. Sin (Φ) = Q/S = VAr/VA. Tan (Φ) = Q/P = VAr/W. The power factor is calculated as the ratio of the real power to the apparent power because this ratio equals cos (Φ).

WebApr 21, 2024 · Since both waveforms are out of phase you cannot simply add their peak (or rms values). If we use this formula Vtot = sqrt ( (V1)^2 + (V2)^2) the result will be 10V which is the supply voltage V1:Peak voltage across the inductor. V2:Peak voltage across the resistor. This strange behaviour comes from the fact that

WebIf they are “in-phase” that is, there is no phase shift then they can be added together in the same way as DC values to find the algebraic sum of the two vectors. For example, if two voltages of say 50 volts and 25 volts respectively are together “in-phase”, they will add or sum together to form one voltage of 75 volts (50 + 25). bridget cavanaugh nasaWebV = IR. where, V = voltage, I = current and R = resistance.

My thinking is that for maximum current, resistance must be minimum. Thus, R1 is not considered which means the voltage drop of R2 is 10V. So, R2 is 1kohm. For minimum, I=2mA, so R1+R2=5kohm, since R2 is 1kohm, R1 must be 4kohm. This is how I deduce.
