Why is resistance less when resistors are join in parallel?
What do you mean? In a parallel circuit, the combined (or effective) resistance is less than any individual resistance.
How are parallel resistors connected?
If you need a resistor of a certain value, and you have no resistors with small enough values,you can create the one you need by connecting several of those you have in parallel.The effective net resistance of resistors in parallel is always less than the smallest individual.And the more resistors you add in parallel, the smaller the net effective resistance becomes.
When resistors are put in parallel with each otherwhat happen to their resistance?
Call the total effective resistance 'R'. If the values of the individual parallel resistors are 'A', 'B', 'C', 'D' etc., then 1/R = (1/A) + (1/B) + (1/C) + (1/D) etc. Or, R = 1 divided by { (1/A) + (1/B) + (1/C) + (1/D) } The more resistors there are in parallel, the SMALLER the effective resistance becomes.
What is the formula for finding resistance for a parallel series?
There is no such thing as a "parallel series". The total effective resistance of many resistors in series is the sum of the individual resistances. It's more than the greatest individual. The total effective resistance of many resistors in parallel is the reciprocal of the sum of the individual resistances' reciprocals. It's less than the smallest individual.
How does electricity react to resistances in parallel and in series?
Resistances in series act just as if they were one single resistor. The value of the single resistor is the sum of the individual resistors connected in series ... Ra + Rb + Rc etc. When several resistors are in series, the effective total is greater than the biggest one. Resistance in parallel act just as if they were one single resistor. The reciprocal of the value of the single resistor is the sum of the reciprocals of the individual resistors connected in parallel ... Total effective resistance = 1 divided by (1/Ra + 1/Rb + 1/Rc + etc.) When several resistors are in parallel, the effective total is less than the smallest one. Once you figure out the effective value of the series- or parallel-combination of many resistors, you handle them as if they were one single resistor, and you can work with the voltage and current: Current through any resistance = (Voltage across it) divided by (its resistance).

How will you join 3 resistors of 2 ohm each so that the effective resistance is 3 ohm?
You can achieve an effective resistance of 3 ohms by connecting the resistors in series. Connect two resistors in series to get a combination of 4 ohms. Then, connect this combination in parallel with the third resistor to achieve an overall resistance of 3 ohms.
How does the effective resistance of four resistors in parallel compared to the individual resistance?
It depends on the values of the individual resistors. But if each resistor is identical, then the total resistance will be one-quarter that of an individual resistor.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.

How many 40 Ω resistors connected in parallel are required to carry 1.5 A on a 12.0 V line?
The required resistance is 12/1.5 = 8Ω.Five 40Ω resistors in parallel have an effective resistance of 8Ω.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the effective resistance of the three resistors?
The effective resistance of those three resistors in parallel is 20 ohms. And it makes no difference what the power source is, or whether they're even connected to a power source at all. As soon as those three resistors are in parallel, their effective resistance is 20 ohms immediately, even if they're still in the drawer.

What is the difference between connecting resistors in parallel and in series?
When resistors are connected in series, the total resistance is the sum of the individual resistances. When resistors are connected in parallel, the total resistance is less than the smallest individual resistance.

What is the totall resistance of infinit number of pararell resistors?
Adding more resistors in parallel always decreases the total effective resistance.So the total effective resistance of an infinite number of them would be zero ohms.Nice ! To build a superconducting ring, all you need is an infinite number of resistors.You don't need the liquid helium, and it superconducts at room temperature !
