When you are dealing with DC voltages polarity is very important. Inside the ammeter is a coil through which the circuit amperage flows. Inside this coil is connected a steel armature of the meter movement. The more current is applied through the coil, the more the steel of the meter movement is drawn into the coil and this in turn moves the needle on the face of the meter to move further up the scale. If the coil polarity is reversed the magnetic field in the coil is reversed and the steel armature is driven in reverse. So instead of the meter movement moving up the scale it is driven to the zero end of the meter scale and it hammers up against the stop pin on the scale face.
Positive + Negative -
These are contact points of battery .
Yes
They are the negative and positive terminals. Higher potential andl ower potential terminals
Conventional current flow is from positive to negative. Electron flow is from negative to positive
if you are asking about the terminals of a cell then i can tell you.There is a plus(+) sign near the positive terminal and a minus(-) sign near the negative terminal.
anode positive potential cathode negative potential
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
connect the both positive terminals together and both negative terminals together. use a multimeter to check any positive and negative terminals
from negative to positive.
positive and negative terminals and the battery case
It is a battery.
