We are dealing with power in circuits.
Power in circuits:
We also have resistors in series.
Given: The circuit below, R2 = 20 kOhms, VS = 12V, and R1 starts at 100 kOhms and is turned down to 20 kOhms. Find: a) the power absorbed in R2 when R1 = 100 kOhms, and b) the power absorbed in R2 when R1 = 20 kOhms.
