First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
A Transistor can be biassed in two ways Forward bias and Reverse bias A transistor is said to be forward bias if the positive of the transistor is connected to the positive terminal of the battery and negative to the negative terminal of the battery.A Transistor in the converse condition is known as reverse biassed
You need to apply an external voltage across the diode. The negative terminal must be connected to the N type material.
To jump start an engine via the battery; the remote battery and the host battery, being of the same voltage, should be connected in parallel. That is positive terminal to positive terminal, negative to negative.
Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.

A DC voltage must have a polarity, however this polarity is always in reference to some common point and has no meaning on its own, the same with voltage. Usually this common point is the circuit ground, which may or may not be earth ground. Example: A household AA battery has a positive and a negative terminal, the positive terminal is +1.5v in relation to the negative terminal, and the negative terminal is -1.5v to the positive terminal.
No. The DC output from the voltage regulator is connected directly to either the positive terminal of the battery or the hot side of the starter relay on some older models.
When the polarity of the battery is such that electrons are allowed to flow through the diode,then the diode is said to be forward-biased. Conversely, when the battery is "backward" and the diode blocks current, then the diode is said to be reverse-biased. A diode may be thought of as like a switch: "closed" when forward-biased and "open" when reverse-biased.
Connecting batteries + to - is said to be connecting them in series. The voltage from two batteries in series will be additave. So two 1.5 volt batteries in series will give you 3.0 volts.
