QUESTION:

Consider the combination of resistors shown in Figure P 3.4-15. Let \(R_{\mathrm{p}}\) denote the equivalent resistance.

(a) Suppose \(50 \Omega \leq R \leq 800 \Omega\). Determine the corresponding range of values of \(R_{\mathrm{p}}\).

(b) Suppose, instead, R = 0 (a short circuit). Determine the value of \(R_{\mathrm{p}}\).

(c) Suppose, instead, \(R=\infty\) (an open circuit). Determine the value of \(R_{\mathrm{p}}\).

(d) Suppose, instead, the equivalent resistance is \(R_{\mathrm{p}}=150 \Omega\). Determine the value of R.
