It is required to use a FULL-wave rectifier to design a dc power supply that provides an average dc output voltage of 15 V. A maximum ripple voltage of ±1 V is allowed on the output voltage. The output voltage will feed a load resistance of 250 Ω. Assume a sinusoidal input voltage with the frequency of 60 Hz. Do not include a Zener diode in your design. (Assume V_D0)* = 0.7 V). a) Draw the circuit diagram. b) Calculate...
A length of aluminum wire is connected to a precision 10.00-V power supply, and a current of 0.4212 A is precisely measured at 27.0 ∘C. The wire is placed in a new environment of unknown temperature where the measured current is 0.3804 A . --------------------------------------------------------------------------------------------------------------------------------------------------- For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 4.00 −kΩ−kΩ resistor from a carbon resistor and a Nichrome wire-wound resistor connected...
