Question

A student constructed a series circuit consisting of a 12.0-volt battery, a 10.0-ohm lamp, and a
resistor. The circuit does not contain a voltmeter or an ammeter. When the circuit is operating, the
total current through the circuit is 0.50 ampere.
Calculate the power consumed by the lamp. [Show all work, including the equation and substitution
with the units.]

2 Answer

  • The power dissipated across a component can be calculated through the formula P=I^2xR

    Substituting the values in we get P=(0.5)^2x10=2.5W
  • The power dissipated across a component can be calculated through the formula P=I^2xR

    Substituting the values in the formula we get

     P=(0.5)^2x10=2.5W

    What is power ?

    Power is the rate at which work is done.” The SI unit for power is the watt (W).

    “It is the work done in unit time.“

    Power is the rate of doing an activity or work in the minimum possible time. It is the amount of energy transferred or converted per unit time where large power means a large amount of work or energy.”

    For example, when a powerful car accelerates speedily, it does a large amount of work which means it exhausts large amounts of fuel in a short time.
