Meaning and measurement of negative resistance
(A negative value times a positive value is a negative value.) When voltage is applied to a passive device that exhibits negative resistance in some part of its response curve, the device outputs power, but that happens only during the period when voltage as a function of current is negative.
How to Check Your Car Battery & Battery Cables
There are two battery cables: the positive and the negative. The positive battery cable connects the battery to the starter motor and other points of the car''s electrical system. Meanwhile, the negative car battery cable connects the battery to a common ground.
resistance
V : is the voltage of the battery. I : is the current that flow in the wires, the resistor, and the led. R : is the total resistance of the circuit. Let''s calculate it first then understand why the resistor is at the positive terminal: You are using 2 * AA battery. Each AA battery has 1.5 volts.
21.2: Electromotive Force
Battery testers, such as those in Figure (PageIndex{6}), use small load resistors to intentionally draw current to determine whether the terminal voltage drops below an acceptable level. They really test the internal resistance of the battery. If internal resistance is high, the battery is weak, as evidenced by its low terminal voltage.
