Question

Three resistors are connected in the circuit shown below. The emf of the battery is 12.0 Vand the resistors have the following values: R CR, and R2 R/c, where R 29.0 n and c is a positive number between 0 and infinity. R3 is an unknown constant value. (a) As the value of capproaches zero, the current through the battery approaches 0.200 A. What is the resistance of R3? (b) What does the value of the current through the battery approach as c approaches infinity? (c) If the value of c is set to 2.50, determine the following (i) The equivalent resistance of the circuit (ii) The current through R2
