To obtain a higher voltage, batteries should be connected in series. In a series connection, the positive terminal of one battery is connected to the negative terminal of the next, which allows the voltages of each battery to add together. For example, connecting two 1.5V batteries in series results in a total voltage of 3V. This method increases the overall voltage while maintaining the same capacity (amp-hour rating) as a single battery.

Why root 3 used in 3 phase system?
In a 3 phase, star connected system, the phase to phase voltage and phase to neutral voltage is calculated using root 3. That is, phase to phase voltage is root 3 times phase to neutral voltage. Also to calculate three phase power the voltage and current is multiplied by root 3 to obtain 3 phase power with unity power factor.AnswerIf you vectorially-add two quantities that are displaced from each other by 120 degrees, then the resulting quantity will be 1.732 (i.e. the square-root of 3) longer. Try it for yourself.So, for a wye (star) connected system, the phasor (vector) sum of two phase voltages will result in a line voltage that is 1.732 times larger than a phase voltage. For a balanced wye (star) connected load, the phasor sum of two phase voltages will result in a line current that is 1.732 larger than a phase current.
How can calculate transformer ratio if out put donor?
To calculate the transformer ratio when the output voltage is known, you can use the formula: Transformer Ratio (Turns Ratio) = Output Voltage (Secondary Voltage) / Input Voltage (Primary Voltage). If you're given the output voltage and the input voltage, simply divide the output voltage by the input voltage to obtain the turns ratio. This ratio indicates the relationship between the number of turns in the primary coil to the number of turns in the secondary coil.
How is the program of pso written in in matlab...For eg i want to obtain optimal position for svc for voltage stability..how will b program..also how to create that program from algorithm..?
The program of PSO in Matlab to obtain optimal position for SVC voltage stability will need written in the standard format beginning with the stability grid.
Why the maximum voltage is to be multiplied by 0.707 in case of series LCR to obtain bandwidth?
The factor of 0.707 is used to convert the peak, or maximum voltage or current, into the corresponding root-mean-square (r.m.s.) value. it does not have anything to do with 'bandwidth'.
Why is three phase voltage 400 V when single phase is 230 single phase 1.73 3 phase. what is 1.73?
I will try and make this as simplified as possible. The secondary side of transfomers are connected in star - which means there is a neutral / earth connection. If you measure between a LINE to LINE ('line voltage') voltage you will measure 400V, but now we have introduced the neutral / earth and we measure between LINE to NEUTRAL ('phase voltage) 's LINE to EARTH we will get 230 V. The reason for this is that, because the phase voltages are displaced, in time, by 120 electrical degrees, you must add them vectorially to obtain the line voltage. And the vectorial sum of two 230-V phase voltages, displaced by 120 degrees, is 400 V -or 1.732 times either of the phase voltages.
How are batteries connected together to obtain more current capacity?
A way of connecting batteries together to provide more current is to connect them in parallel. This allows more capacity at the same voltage. If the batteries were connected in series the voltage would be increased.
Can you wire batteries of different voltages in series to obtain a specific voltage?
Yes you can. Though it is not recommended as it usually shortens the life of one of the batteries used.
How do you connect 2 6 volt batteries in parallel to make 12 volts?
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.
How may you connect several dry cell to obtain the biggest voltage?
The largest voltage results when all of the individual cells are connected in series,just like all the 'batteries' in one of those 3-foot-long flashlights...... +cell- ..... +cell- ..... +cell-..... +cell- ..... +cell- ..... etc.
How do you wire four 12 volt batteries to get 36 volts and 48amps?
Four 12V batteries may not be connected end to end to obtain 36 Volts. But four 12V batteries can be connected end to end to provide 48V and push 36 amps. The actual answer to your question suggests that you drop one 12V battery and use three, not four 12V batteries end to end to obtain 36V.
Why 5KV voltage is applied to Megger for insulation resistance measurement?
It is a easy voltage to obtain and can check for breakover in the insulation. The voltage is higher then what would be put through most wire and shows any weakness.
Describe the proper placement of a voltmeter in a circuit?
To measure voltage in a circuit, the voltmeter should be connected in parallel across the component or portion of the circuit where the voltage is to be measured. Ensure the voltmeter is set to the appropriate voltage range before making the connection. It is important to place the voltmeter correctly to obtain an accurate voltage reading without affecting the circuit's operation.
How much voltage is 4 9 volt batteries?
> 36 volts. > Originally answered by Contributor This is a trick question correct right??? Is the question how many volts are four, 9 volt batteries or is it how many volts are in a 49 volt battery(if it exists)? Four nominally rated 9 volt batteries wired in series would yield about 36 volts while the same four wired in parallel would provide ~4 times more current or last about 4 times longer in the same circuit. The battery rating shown on the battery is a nominal voltage the actual voltage output of the battery can be higher or lower. First different technology batteries actually produce physically different output voltages. ie: a battery is made of cells and dependent on the type of chemistry the cell is made from the actual per cell output can very from 1.2 volts up. Batteries made with Lead plates surrounded in Sulfuric Acid (typical car batteries) can produce 2.0 volts per cell (measured open circuit). Lap top Batteries can be about 3.6 - 3.7 volts per cell while alkaline batteries (flashlight batteries) start out at 1.5 volts. To obtain higher voltage battery outputs the cells are wired in series and the voltages adds up. To obtain more current capacity cells are wired in parallel. These are nominal voltages the circuit drain causes the cell voltage to drop eventually the battery output is to low to power the application it is used in at which point it is considered dead. Even though there may still be some energy left in the battery. A good simple explanation of battery characteristics can be found at the first related link below. A more detailed and technical explanation can be found on Wikipedia at the second related link below.
What will happen if single phase load is connected to three phase circuit?
To obtain a single-phase supply from a three-phase supply, the single-phase load must be connected either (a) between any pair of line conductors, or (b) between any line conductor and the neutral conductor. Of course, the voltage obtained from either of these connections must match the voltage rating of the load.
How can you obtain three time voltage across potential coil of wattmeter?
The voltage applied to the voltage coil of a wattmeter must not exceed the voltage rating of that coil.
Can you wire 3 6 volt batteries to get 12 volts?
Yes, you can wire three 6-volt batteries in series to achieve a total voltage of 18 volts, not 12 volts. To get 12 volts, you would need to use two 6-volt batteries in series. By connecting the positive terminal of one battery to the negative terminal of the other, you can obtain the desired 12 volts across the remaining terminals.
How do you know the primary or secondary side of a transformer?
The primary side is usually labelled 'H', the secondary is often labelled 'L'.Primary wiring will often be smaller, since the current carrying capacity doesn't have to be as high on the primary side.The best thing to do would be to check with the manufacturer. They should have documentation stating what is primary and secondary.CommentThe above answer only applies to step-down transformers. The simple answer is that the primary winding is the winding connected to the supply, whereas the secondarywinding is the winding connected to the load. These terms have nothing to do with voltage levels.
