What is the power developed by a 22kΩ component with 9.0V applied to it?

The power P developed by a component can be calculated using Ohm's law and the formula for power.

Step 1: Convert the resistance to ohms. In this case, it's already given in ohms (22kΩ = 22000Ω).

Step 2: Use Ohm's law (V = IR) to find the current I. Rearrange the formula to I = V/R.

Step 3: Substitute the given values into the formula. I = 9.0V / 22000Ω = 0.000409 A (rounded to six decimal places).

Step 4: Use the formula for power P = IV.

Step 5: Substitute the values into the formula. P = 0.000409 A * 9.0V = 0.00368 W or 3.68 mW.

So, the power developed by the 22kΩ component with 9.0V applied to it is approximately 3.68 mW.
