Say you were trying to find the equivalent resistance based on this circuit. How would v1 be found? (a specific value wouldn't be needed, just the step-by-step process to find the values.)
The 12-V source in Figure P2.32 is delivering 36 mW of power. All four resistors have the same value R. Find the value of R.
The voltage divider network of Figure P2.58 isexpected to provide 5 V at the output. The resistors,however, may not be exactly the same; that is, theirtolerances are such that the resistances may not beexactly 5 k.a. If the resistors have ±10 percent tolerance, find theworst-case output voltages.b. Find these voltages for tolerances of ±5 percent.Given: V = 10 V, R1 = 5 k, R2 = 5 k.
