A voltage source an IR drop of 40 volts across a 20 ohms R1, 60 volts across a 30 ohms R2, and 180 volts across a 90 ohm R3, all in series. How much is the applied voltage?

Calculate the peak voltage across R2 in the diagram R1 = 1 kohm, R2 = 680 ohms, supply voltage is 10V RMS     5.73V peak     10V peak     4.04V peak     1.75V peak

15. Which of the following conductors in a typical separable connection plug and receptacle has a firstmake, last-break feature?A. The neutral grounded conductorB. The equipment grounding conductorC. A center wye conductorD. The grounded delta conductor

Determine the total resistance and total current, as well as the current, voltage and power that exists in each of the resistances of the following resistive mixed type circuit

How does the concept of duality apply to electrical circuits?

The primary voltage on the transformer in Figure 2–46 (p. 96) is 120 V rms and NP : NS = 15:1. Diode voltage drops are 0.7 V. (a) What should be the value of RL if the average current in RL must be 0.5 A? (d) Is it alright to measure with an oscilloscope both the input and output waveforms at the same time in Figure 2-46?  Why or why not?
