1) The resistances of commercially-available discrete resistors are restricted to particular sets. For example, the available values of resistors with 10% tolerance are selections from the E12 set multiplied by a power of ten from 100 through 10s. The E12 set is: E12-10,12, 15, 18,22,27,33,39,47,56,68, 82) Thus, you can buy 10% resistors with a nominal resistance of 3300 or 33M. but not 350n. Furthermore, the tolerance a 10%...

We have a 15V source and a load that absorbs power and requires a current varying between 0 and 100mA. The voltage across the load must remain between 4.7V and 5.0V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available. Also, give the minimum power rating for each resistor. Please show all workings & calculations on how you came to your answer.

In a radio frequency circuit, a resistance of 1752 Ω serves as a load at the end of a 50 Ω transmission line. We wish to connect an inductor, L, in series to the input of the line so that a source with an output impedance of 50 Ω does not see reflections. No need to know the frequency to solve the problem (a) Determine the minimum length of the transmission line in terms of wavelengths. (b) Determine the value...
