如果其呈现线性关系，测试结果应该通过适当的统计学方法(例如，以最小二乘方来计算回归线)来确立。

If there appears to be a linear relationship test results should be established by appropriate statistical methods (e. g. by calculation of a regression line by the method of least squares).

如果电压不变，电阻增加1倍，电流就减小二分之一。

If the resistance is doubled without changing the voltage, the current bees only half as strong.
