I'm going to take this as "How do you connect resistors is series?" just connect one wire of the first resistor to one wire of the second.

How will you get 3 ohm resistance using 2 ohm resistance?
connect 2 2ohm resistors in parallel and connect it to a series 2ohm resistor
Why we connect high resistance in series to a motor?
Reduce current - reduce power.
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
How can you connect resistors to produce an equivalent resistance which is the same as the resistance of each individual resistor?
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
How do you place 3 resistance to get the total resistance of 1 ohm?
It depends on the resistance of each resistor. If each resistor, for example, is 0.333 ohm, then you could connect them in series. If each resistor, for example, is 3 ohms, then you could connect them in parallel.
Why should you be the internal resistance of the very few Amitr?
ammeter connect in series in circuit to measure the current, if the Ammeter have a high resistance it would effect the voltage value because there will be a drop voltage over the internal resistance of the Ammeter, so we desgin the ammeters with very low resistance...
If a 1 ohm resistor is parallel with a 100 ohm resister what's the total resistance?
If two 1-ohm resistors are connected in parallel, their resistance is 0.5 ohms. If they are connected in series, their resistance is 2 ohms. It is not possible to connect only two resistors in series parallel.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
What should you do to convert a galvano meter into volto meter?
Connect a large but precisely known resistance in series with the galvanometer. For example, if you connect a 1-Megohm resistor in series with it, then the galvanometer will indicate 1 microampere of current when it's connected across a potential difference of 1 volt ... quite a sensitve voltmeter.
How can you get 25ohm total resistance from 100 resistors having 1 ohm resistance?
Connect 50 of them in series. This would have 50 ohm as equivalent. Same way have another 50 pieces in series. This again would have 50 ohm as effective value. Now connect these in parallel to each other. Now the effective would become as 25 ohm.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
How galvanometer measure the exact voltage with series high resistor?
Assuming galvanometer has zero or negligible internal resistance. If u connect resistor R>>RL(Load resistance) and connect it parallel to RL, it will hardly cause any change in voltage across load resistance. Suppose small current Ig goes through galvanometer. Since galvanometer have zero internal resistance, Voltage across RL = Voltage across R = IgR
