The current flowing in resistor R2 is given as: IR2 = VS ÷ R2 = 12V ÷ 47kΩ = 0.255mA or 255μA.

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 WebV = IR. where, V = voltage, I = current and R = resistance. From the equation we can say if the current is constant then the potential difference is directly proportional to the resistance. …

WebApr 13, 2024 · Here is the figure mentioned above. 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...
