Question

What is the resistance of R1 ? Are R2 and R3 connected in series or parallel? Based on your answers to Items 3 and 5, what is the equivalent resistance to the combination of R2 and R3? If you drew this equivalent resistance into the circuit as only one resistor Requivalent, would R1 and Requivalent be connected in series or parallel? What is the sum of R1 and Requivalent? Using Ohm's law , what is the total resistance in the circuit? How are these related?

Explanation / Answer

We know,
V = I * R
R = V/I
R1 = 3.04 / 0.10
Resistance of R1 = 30 ohm

R2 & R3 are connected in Parallel.

1/Req = 1/R2 +1/R3
Req = R2 * R3 / (R2+R3)
Req = 50 * 70 / (50 +70)
Req = 29.166 ohm

R1 and Req are connected in series.

Sum of R1 and Req = 30 + 29.166 = 59.166 ohm

Total Resistance in the circut = 59.166 ohm
