Quizplus · Accepted Answer

The input impedance of a circuit can be calculated using the formula for parallel resistances when the resistors are in parallel. In this case, without the specific values or the figure mentioned, the correct answer typically involves calculating the equivalent resistance of the circuit components presented. Since the question does not provide the necessary details or values to perform calculations, the correct answer (B) is based on the assumption that the question provides enough information to deduce that 186 ohms is the approximate input impedance. This could involve specific values of resistors, the configuration of the circuit, or other components affecting the impedance.
