How much energy does an electric hair dryer use if it draws 8.3 amps of current when using 120 volts for 5.0 minutes?

0.083kwh is the answer your welcome

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
