Aflashlight has a resistance of 2.4 . what voltage is applied by the batteries if the current in the circuit is
2.5 a?
0.96
v 1.0
v 4.9
v 6.0 v

Using V=IR, I is 2.5 and R is 2.4
 therefore answer is 2.4 multiply by 2.5 which is equal to 6v

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.
