The voltage of AC (Alternating Current) is not a fixed value like DC (Direct Current). Instead, it continuously changes in magnitude and direction over time.
### **Key AC Voltage Terms:**
1. **Peak Voltage (Vp or Vmax)** – The maximum voltage reached in one cycle.
2. **Peak-to-Peak Voltage (Vpp)** – The total voltage difference between the positive and negative peaks.
3. **Root Mean Square (RMS) Voltage (Vrms)** – The effective voltage of AC, which is commonly used in calculations because it gives the same heating effect as a DC voltage.
### **Common AC Voltages:**
- **Household Voltage:** In most countries:
- **230V RMS** (Europe, Asia, etc.)
- **120V RMS** (USA, Canada, etc.)
- **Power Transmission Lines:** Ranges from **thousands to hundreds of thousands of volts** (e.g., 110kV, 220kV) for efficient power transfer.
Since AC voltage varies, RMS voltage is usually mentioned. For example, if the household voltage is 230V RMS, the peak voltage would be:
\[
V_{peak} = V_{rms} \times \sqrt{2} \approx 230V \times 1.414 \approx 325V
\]
