Power Triangle and Power Factor in AC Circuits
Power Factor in AC Circuits. Power factor, cos(Φ), is an important part of an AC circuit that can also be expressed in terms of circuit impedance or circuit power. Power factor is defined as the ratio of real power (P) to apparent power (S), and is generally expressed as either a decimal value, for example 0.95, or as a percentage: 95%.
8.3: Capacitors in Series and in Parallel
The total capacitance of this equivalent single capacitor depends both on the individual capacitors and how they are connected. Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily calculate the total capacitance. These two basic combinations, series and parallel, can ...

What Happens if We Connect a Polar Capacitor the Wrong Way?
What Happens When You Connect an Electrolytic Polarized Capacitor in The Reverse Polarity? There are different types of capacitors such as polar (fixed capacitors e.g. electrolytic, Pseudo-capacitors, ELDs, and super-capacitors) and non-polar capacitors (ceramic, mica, film, paper and variable capacitors). Capacitors play an active and …
20.5: RC Circuits
In a series RC circuit connected to an AC voltage source as shown in, conservation of charge requires current be the same in each part of the circuit at all times. Therefore we can say: the currents in the resistor and capacitor are equal and in phase. (We will represent instantaneous current as i(t). ) Series RC Circuit: Series RC circuit.
