Answer: The energy drawn by electric hair dryer is 2,98,800 J
Explanation:
To calculate the power of the electric hair dryer, we use the equation:
[tex]P=I\times V[/tex]
where,
P = power of electric hair dryer
I = Current of electric hair dryer = 8.3 A
V = voltage of electric hair dryer = 120 V
Putting values in above equation, we get:
[tex]P=8.3\times 120=996W[/tex]
To calculate the energy of electric hair dryer, we use the equation:
[tex]E=P\times t[/tex]
where,
E = energy of electric hair dryer = ?
P = Power of electric hair dryer = 996 W
t = time taken = 5.0 min = 300 s (Conversion factor: 1 min = 60 sec)
Putting values in above equation, we get:
[tex]E=996\times 300=2,98,800J[/tex]
Hence, the energy drawn by electric hair dryer is 2,98,800 J
