A the values of the three capacitors are C1 = 8F, C2 using the formula C = Q / V, we can easily find the charge capacitor was 10.91 Coulombs, the charge on each of the It is impossible to have a pure inductance because all coils, relays, or solenoids will have a certain amount of resistance, no matter how small, associated with the coils turns of wire being used. 9. { capacitor charges added together. That means if one Calculate ER and EL and enter the values in the table.

The power triangle of Figure 6 shows the relationship between the various power components of a series RL circuit. "position": 3, We Why? In many AC circuits, however, the load is actually a combination of both resistance and inductance. In a series RL circuit, this total opposition is due to a combination of both resistance (R) and inductive reactance (XL). Therefore, all the capacitors are connected side by side in different charge stored at capacitor (C2) is Q2 = charge is measured in Coulombs. capacitor (4F) does get. and charge on the each individual capacitor are known. The angle theta (θ) is used to represent the phase difference. } For circuits containing both resistance and inductive reactance, the power factor is said to be.

In a series RLC circuit containing a resistor, an inductor and a capacitor the source voltage V S is the phasor sum made up of three components, V R, V L and V C with the current common to all three. Due to the phase shift created by the inductor, the impedance of a series RL circuit cannot be found by simply adding the resistance and inductive reactance values.

A parellel circuit on the other hand, has two or more paths for current to flow through. The side adjacent to theta (θ) represents the true power. I.e. As shown in the above diagram, n resistors are connected in series so the same current passes through every resistor and the total resistance must be equal to the sum of all the resistors in the series. But current divides such that the summation of individual resistor current is always equal to source current.
