Question

Three resistors (234 Ω, 159 Ω, and 301 Ω) are connected in a DC circuit. Determine the equivalent resistance if:

a. Each resistor is connected in series.

R_eq = ______ Ω

b. The resistors are connected in parallel to each other.

R_eq = _______ Ω

Answer 1

Given resistances

R1 = 23412

R3 Ξ 3012

When resistances are connected in series then

Req = R1 + R2 + R3

Req = (234 + 159+ 301)

Now for parallel

1 + + R Ri R2 R3

1 1 1 + + R 234 159 301

R= 722

In parallel combination answer is 72 ohm.

Thanks for asking.
