Answer:

ANSWER:The needed current is 30 amperes.

Variation is a relationship of two or more variables. We say that the two variables vary directly when these variables go in the same direction. Meaning, if one variable increases, the other one also increases. We say that the two variables vary inversely when these variables do not go in the same direction.

Types of Variation

1. Varies Directly

2. Varies Inversely

3. Joint Variation

4. Combine Variation

Suppose a variable, , varies directly as , then there exist a constant, , such that satisfies.

Suppose a variable, , varies inversely as , then there exist a constant, , such that satisfies.

In the context of the problem, since the current, , varies directly as the electromotive force , then we know that there is a constant, , such that satisfies. Also, since current, , varies inversely as the resistance . Simultaneously, we have .

First, solve the value of by substituting , , and into the formula.

Second, using the same formula, substitute the value of , , and to find the current.

Thus the needed current should be 30 amperes.
