The electrical energy used by a 400 W toaster that is operating for 5 minutes will be 120,000 J.Option C is correct.
The rate of the work done is called the power output. It is denoted by P.Its unit of a watt. It is the ratio of the work done or the enrgy to the time period.
The given data in the problem is;
E is the electrical energy
P is the power output = 400 W
t is the time period = 5 minutes
The power output is given as;
[tex]\rm P= \frac{E}{t} \\\\\ E= P \times t \\\\\ E= 400 \times 300 \\\\\ E=120,000 \ J[/tex]
Hence the electrical energy used by a 400 W toaster that is operating for 5 minutes will be 120,000 J.Option C is correct.
