If a 6000-ohm resistor is connected to an outlet that provides a 120-V, 60 Hz sinewave. How much power would be used?
The power consumed when a resistor with resistance R is connected across a voltage source V is given by P = V^2/R.
For a resistor of 6000 ohm and a voltage source V ` `= 120 V, the power consumed is (120^2)/6000 = 2.56 W.
The amount of powered consumed by the resistor is 2.56 W.
