Corrosion on the positive terminal is caused by electrolysis, due to a mismatch of metal alloys used in the manufacture of the battery terminal and cable connector.
32.
Two-stage systems, or " tandem accelerators ", start with a source of He " ions and position the positive terminal at the center of the acceleration tube.
33.
In a diode, the anode is the positive terminal at the tail of the arrow symbol ( flat side of the triangle ), where current flows into the device.
34.
When describing AAA, AA, C, sub-C and D size cells, the negative electrode is connected to the flat end, and the positive terminal is the end with the raised button.
35.
Remove the transistor and the diode D5, reverse the polarity of the batteries such that the positive terminal connects to the anode and the negative terminal connects to the cathode.
36.
The total current flowing into the positive terminal of the circuit is equal to the sum of the current flowing through the inductor and the current flowing through the capacitor:
37.
The wheel is connected to the positive terminal of the DC power supply through a carbon brush whereas the electrode is connected to the negative pole of the power supply.
38.
In making the connections, clamp one cable first to the positive terminal ( marked Pos or + ) of the dead battery, then to the positive post of the good battery.
39.
A DC ammeter is thus sensitive to which way round it is connected; most are marked with a positive terminal, but some have centre-zero mechanisms and can display currents in either direction.
40.
Current can flow from lower voltage to higher voltage, but only when a battery, chemical reactions provide the energy needed for ion current to flow from the negative to the positive terminal.
