1. What is Rectified DC Voltage?

The rectified DC voltage is the output voltage of an AC-to-DC rectifier circuit, accounting for voltage drop due to current flow through circuit resistance. It's crucial for power supply design and analysis.

2. How Does the Calculator Work?

The calculator uses the rectified voltage equation:

Where:

• \( V_{ac} \) — AC input voltage (RMS)
• \( I \) — Current through the circuit (A)
• \( R \) — Total circuit resistance (Ω)
• \( \sqrt{2} \) — Conversion factor from RMS to peak voltage

Explanation: The equation calculates the theoretical maximum DC voltage (AC peak) minus the voltage drop caused by current flowing through circuit resistance.

3. Importance of Voltage Calculation

Details: Accurate DC voltage calculation is essential for designing power supplies, determining proper component ratings, and ensuring correct operation of electronic circuits.

4. Using the Calculator

Tips: Enter AC voltage in RMS volts, current in amps, and resistance in ohms. All values must be valid (voltage > 0, current ≥ 0, resistance ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use √2 in the calculation?
A: √2 converts RMS voltage to peak voltage, which is the maximum voltage in an AC waveform that would be rectified to DC.

Q2: What affects the voltage drop?
A: The drop is proportional to both current (I) and resistance (R) according to Ohm's Law (V = I×R).

Q3: Does this account for diode drops?
A: No, this is the theoretical maximum. Real circuits will have additional drops from diodes (typically 0.7V per diode in silicon rectifiers).

Q4: When would the voltage drop be zero?
A: When either current is zero (no load) or resistance is zero (ideal conductors).

Q5: How accurate is this calculation?
A: It provides the theoretical maximum DC voltage. Real-world values will be lower due to additional factors like transformer regulation and capacitor effects.
