Problem 12-58 Resistor network - Part 2 - A

Diagram of circuit.

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:

Diagram of circuit with resistors.

The equivalent resistance \(R\) of this circuit is given by:

(A)  \(1/R = 1/150 + 1/214 + 1/250\)

(B)   \(R = 150 + 214 + 250\)
