Respuesta :
P = power rating of the electrical toaster = 1200 watts
t = time of operation = 30 sec
E = total electrical energy
Total electrical energy is given as
E = P t
inserting the above values
E = 1200 x 30
E = 36000 J
Answer : Total electrical energy is 36000 J.
Explanation :
It is given that,
Power of electric toaster, P = 1200 Watts
Voltage, V = 120 Volts
Time, t = 30 s
Electric energy is defined as the product of the power and the time taken.
[tex]E=Pt[/tex]
[tex]E=1200\ W\times 30\ s[/tex]
[tex]E=36000\ J[/tex]
Total electrical energy used to operate the toaster for 30 seconds is 36000 J.
