Question

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

Answer 1

     The energy provided by a load is given by:

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

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

Answer 2

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.
