Indicate whether the statement is true or false.The voltage divider network of Figure P2.52 is designed to provide vout = vS/2. However, in practice, the resistors may not be perfectly matched; that is, their tolerances are such that the resistances are unlikely to be identical. Assume vS = 10V and nominal resistance values of R1 = R2 = 5 k?. a. If the resistors have ±10 percent tolerance, find the expected range of possible output voltages. b. Find the expected output voltage range for a tolerance of ±5 percent.
