(A) Standing waves are created by two identical waves reflecting off each other
(B) a general definition of a wave interference is, when more than on wave meet and interact in the same medium
Hope this helps :)
The relationship between the voltage and the current in the circuit is:

where

is the voltage difference, R the resistance of the circuit (and therefore, the resistance of the battery) and I the current flowing in the circuit. By using I=19 A and

, we can find the internal resistance of the battery:
