An operating 100.-watt lamp is connected to a

120-volt outlet. What is the total electrical energy

used by the lamp in 60. seconds?

(1) 0.60 J (3) 6.0 × 10^3 J

(2) 1.7 J (4) 7.2 × 10^3 J

Verified Answer :

The energy provided by a load is given by:

\(E=P*\Delta t\)
 
     Entering the unknowns, comes:

\(E=P*\Delta t \\ E=100.60 \\ \boxed {E=6*10^3J}\)

Number 3

Option C) 6.0 × 10³J is the correct answer.

Hence, the total electrical energy used by the lamp in the given time is 6.0 × 10³J.

Given the data in the question;

  • Power of lamp; \(P = 100W = 100J/s\)
  • Voltage; \(V = 120V\)
  • Time elapsed; \(t = 60s\)
  • Electric Energy; \(E = \ ?\)

Eneregy

Energy is simply the ability or capacity to do work.

Energy can be expressed as Power multiply by time.

\(E = P * t\)

Where P is power and t is time elapsed.

To determine the total electrical energy used by the lamp, we substitute our given value into the expression above.

\(E = P * t\\\\E = 100J/s\ *\ 60s\\\\E = 6000Js/s\\\\E = 6.0*10^3J\)

Option C) 6.0 × 10³J is the correct answer.

Hence, the total electrical energy used by the lamp in the given time is 6.0 × 10³J.
