Resistance

CodeChefRating 1761Open on judge ↗

The electrical resistance is the opposition to the passage of electric current. If two resistors with resistance R1 and R2 are connected to each other, the resultant resistance R depends on how their ends are connected. If they are connected in Series, they simply add up to give R = R1 + R2. If they are connected in Parallel, its given by the equation 1/R = 1/R1 + 1/R2. This is shown below. We ha
