I believe they are called nonohmic materials. According to ohms law the current trough a current carrying conductor is directly proportional to the potential difference (voltage) at a constant resistance. Non-ohmic conductors or materials are those materials that do not obey the ohms law, their resistance increases as the current increases. Ohmic materials are those that obeys the ohms law such that the voltage and current are proportional- doubling the potential difference doubles the current.

Explanation:
Let solve the program using Java programming language
Method: method means group of statements to perform some operation.
let call the method sum.
Parameters: list of variables that are use in the method for declaration.
<u>The code</u>
public int sum (int number)
int answer;
if (number == 1)
answer = number;
else
{
int half = number/2;
int span = number - half;
answer = sum(half) + sum(span) + (half * span);
}
answer result;
}
Firstly we defined the method called sum(), the method takes only one parameter which is number and return the answer(sum of the integers 1 and N).
if the number is equal to 1, so it will return the number and if the number is not equal to 1 it will divide the number by 2 and get the span(span used to shift upper range).And result will add sum of half, sum of span and product of half span.
