🔍 Key Concepts

• Power factor correction in AC circuits and how capacitors affect phase angle between voltage and current • What happens to voltage and current in a transformer primary when a reactive component (inductor or capacitor) is added in series • The difference between power factor correction, voltage regulation, and rectification

💭 Think About

• Think about whether a capacitor in series will increase or decrease the net reactance of the primary circuit, and how that affects the phase relationship between voltage and current • Consider which component or circuit is typically used to convert AC to DC, and whether a single series capacitor can perform that function on its own • Ask yourself what "output voltage regulation" means in transformers and whether a series capacitor on the primary is the standard method to achieve it

✅ Before You Answer

• Verify what series capacitors are commonly used for in AC power systems (transmission lines, motors, etc.) • Confirm the usual method for rectification of AC (what devices are used?) • Check how power factor is defined: the cosine of the angle between voltage and current, and whether adding a capacitor in series can help correct a lagging current caused by inductive load
