# Problem 12-58 Resistor network - Part 2 - A

In the Figure, what is the
(a) current through the $150 \Omega$ resistor?
(b) potential difference across the $250 \Omega$ resistor?
(c) current through the $350\Omega$ resistor?
(d) potential at $\text{point A}$ (assuming zero potential at the negative terminal of the battery)

[Ans. (a) $0.057 \;A$   (b) $14 \;V$   (c) $0.035\; A$  (d) $21 \;V$ ]

Accumulated Solution

$1/R' = 1/350 + 1/550 , \quad R' = 214 \Omega$

Correct!

The equivalent circuit is now:

The equivalent resistance R of this circuit is given by:

(A)  $1/R = 1/150 + 1/214 + 1/250$

(B)   $R = 150 + 214 + 250$
