A full-wave rectifier with a center-tapped transformer supplies a DC of 100 mA to a load resistance of 20 Ω. The secondary resistance of the transformer is 1 Ω. Each diode has a forward resistance of 0.5 Ω. What are RMS values of signal voltage across each half of the secondary as well as dc power supplied to the load?

• A. 2.39 V and 0.2 Watt
• B. 23.9 V and 2 Watts
• C. 0.239 V and 20 Watts
• D. 2.39 V and 2 Watts
