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. However... signode systems thailand limited

WebThe reason for this convention is so the signs of current and voltage come out right when we apply the defining equations for each component, like Ohm's Law for a resistor. Example 1 This 250 Ω250 \,\Omega250Ω250, \Omegaresistor has been labeled using the sign convention for passive components. WebAs the frequency of the voltage, v and the current, i are the same they must both reach their maximum positive, negative and zero values during one complete cycle at the same time (although their amplitudes may be different). Then the two alternating quantities, v and i are said to be “in-phase”. Two Sinusoidal Waveforms – “in-phase” signo de thumbprintingWebThe phrases "Voltage on" and "Voltage across" mean the same thing. One end of the resistor is at a higher potential than the other end. The difference in potential is called the "voltage across" the resistor. It is the nature of resistors that when they have a voltage across them, a current flows. When current flows, there is energy being ... theracane where to buy local

"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) . " - In a resistor v and i are always out of phase

For a capacitor or inductor, the relative signs of and vary over a cycle due to their phase … WebOhm's law says V equals I times R. And what I'm thinking over here or what I used to think over here is I already know the voltage is 50. So then, for two ohm resistor to calculate the current here, I would substitute R as two, V is 50, calculate the current. Then for 40 Ohm resistor, I would put V is 50, that's already given, R is 40.

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). WebPhase angle `tan\ theta=(X_L-X_C)/R` Angle θ represents the phase angle between the current and the voltage. Compare this to the Phase Angle that we met earlier in Graphs of y = a sin(bx + c).

WebNote that V C and V L are approximately three times greater than E, and that V R and E are equal. (The vertical scale for all three traces in each panel is 5.00 V/div.) By far the greatest potentials appear across the capacitor and the inductor, but they are equal and 180° out of phase with each other, so they add to zero, and the potential across the resistor equals … theracare bronxWebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source.
