A light bulb, after it has reached its operation temperature, is connected across a potential difference of 120V while 0.5A of current passses through it. What is the resistance of the light bulb?

  • physics - ,

    E = IR
    120 = 0.5R
    Solve for R.

  • physics - ,

    120/0.5 = 0.5R/0.5

    = 240 ohms
