# Resistive Circuits

Consider the circuit in the attachment when answering the questions posed below.

a) What value of Ix will result in a voltage drop of 16 V across the 10 k Ohm resistor?

b) To reduce cost, it is desired that each resistor in the circuit have the same power rating. Using the results of (a) what power rating - to the nearest 0.1 W - is needed?

#### Solution Preview

Please see attached file for the solution to the given problem.

Solution: We will first simplify the circuit. The rightmost branches 20k and 5k ohms resistors are in parallel and in series with 6k ohms. So we have:

The current across 10k is equal ...
