Question

resistance Ri R2 Ra R3 R1= 10 ohms, R2-2 ohms, R3= 14, R4-4 ohms. 1) (10 pts) Calculate the equivalent resistance that would replace the above resistor network connected to points (a) and (b). 2) (10 pts) Calculate the equivalent resistance that would replace the above resistor network connected to points (c) and (D). 3) (15 pts) Assume an 18 Volt battery connects to the resistor network above such that the negative terminal connects to (a) and the positive terminal connects to (c). If point (D) is grounded (0 volts) then calculate the voltages at points (a), (b), and (c)

Explanation / Answer

1) here, R2,R3 and R4 are connected in series and this combination is in parallel with R1.

1/Rnet = 1/R1 + 1/(R2+R3+R4)

1/Rnet = 1/10 + 1/(2+14+4)

Rnet = 6.67 ohms

2) here, R1,R2 and R3 are connected in series and this combination is in parallel with R4.

1/Rnet = 1/R4 + 1/(R1+R2+R3)

1/Rnet = 1/4 + 1/(10+2+14)

Rnet = 3.47 ohms
