(b) For the circuit shown in Figure Q4 (b) (i) Construct a Thevenin's equivalent circuit for the network external to resistor, R. (ii) A student claimed that the maximum power is delivered by the circuit when the resistant, R is 100. Justify the claim by the student. 2A R 120 19 V- 12 V Figure Q4 (b)

Draw the circuit and show your solution. With 6 V applied, what is the voltage across R2 of a parallel combination of R2 (1 k ), R3 (2 k ), and R4 (1 k ) in series with R1, whose value is 2 k ?

Moving to another question will save this response. Question 9 Four point charges are located at the corners of square 4 cm has been shown in figure Below, each charge is 1.2 NC, the net potential energy stored in the system equals to I.2 nc C 1.2 nc 4 cm 1.2 nc 1.2 nc 4 cm C

Electrical Engineering For the final problem, consider the following circuit diagram: 12 Q 30 V Vx 60 Q 2"Vx B 6) For this circuit, please find and draw: a. The Thevenin equivalent circuit between A and B, using external excitation to find R. b. The Norton cquivalent circuit berween A and B. c. Review section 3-8 from the text. What value load resistor connected between A and B would yield maximum power transfer? How much power woukd this be?

The Quasstion in the pecture

= 200 N are connected such tha Four resistors, R1 = 100 N, R2 = 250 N, R3 = 350 N and R4 the parallel combination of R, and R2 is connected in series with the parallel combination c R3 and R4. The series-parallel combination is then connected across a 24 V DC power suppl A. Draw the schematic diagram and label the circuit elements. B. Calculate the equivalent resistance of the circuit. (Ans. Req C. Find the total current of the circuit, the voltage across each resistor and the current throug each resistor. = 198. 7013 Q)
