average voltage, current

A full-wave bridge rectifier circuit with a 1-kohms load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer having a single secondary winding. It uses four diodes, each of which can be modeled to have a 0.7-V drop for any current. What is the fraction of a cycle does each diode conduct? What is the average voltage across the load? What is the average current through the load?

Circuit output

For the circuit in Fig. P3.105, each utilizing an ideal diode(or diodes), sketch the output for the input shown. Label the most positive and most negative output levels. Assume CR.>>T. Pls see attached.

Two Stage BJT Design

design two stage amplifier and provide the hand calcaulation and draw the ac analysis and dc analysis with the following specfication: Small signal gain >100 Input resistance Ri > 2kΩ Output resistance Ro < 1 kΩ Use BJT with b=100 and ignore (ro). resistance RL= 10kΩ. Single supply voltage of VCC= 6 V Input voltage (vi) and the internal resistance RS vi =0.01 sin(ωt) and RS = 500Ω. hints:you should use common emitter followed by common collector to meet this requirement.your circuit will be similar to the attached file#1.use pi model for easier analysis.you may assume some value of resistance or current to start with if u need like RC or current ... click for more

op am current values

(i) The minimum recommended supply voltages for the 741 op-amp are V+=5V and V-=-5V. Using these lower supply voltages, calculate (a) Iref, Ic10, Ic6, Ic17, Ic13a, and (b) the voltage gains of the input and gain stages for the circuit values in the attached image.
