WebA voltage divider is a simple series resistor circuit. It's output voltage is a fixed fraction of its input voltage. The divide-down ratio is determined by two resistors. Written by Willy McAllister. A very common and useful series resistor circuit … Web• The current flowing in the system is in phase with the source voltage. The power dissipated in the RLC circuit is equal to the power dissipated by the resistor. Since the voltage across a resistor(VR cos(ωt)) and the current through it (IR cos(ωt)) are in phase, the power is 2 ( ) cos( ) cos( ) cos ( ) RR RR pt V tI t VI t ω ω ω = = (1.4)

WebAs with the resistor example, the power is also positive when the instantaneous current and voltage are both negative (below the line). However, because the current and voltage waves are 90° out of phase, there are times when one is positive while the other is negative, resulting in equally frequent occurrences of negative instantaneous power. 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”

WebSo 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. Calculate the current, same thing over here. And we are done. We now know current through each resistor. But do you understand, that's wrong.
