Chapter 3, Problem P 3.6-38

(choose chapter or problem)

Consider the circuit shown in Figure P 3.6-38.

(a) Suppose \(i_3=\frac{1}{3} i_1\). What is the value of the resistance R?

(b) Suppose. instead, \(v_2=4.8 \mathrm{~V}\). What is the value of the equivalent resistance of the parallel resistors?

(c) Suppose, instead, \(R=20 \Omega\). What is the value of the current in the \(40-\Omega\) resistor?

Hint: Interpret \(i_3=\frac{1}{3} i_1\) as current division.
