What is the purpose of resistance?
Resistance doesn't have a 'purpose'; it exists whether you want it or not. You can modify it by adding more resistance in series or in parallel, but you can't avoid it!
How do you find resistance in a parallel circuit?
resistance inparallel decrease in value proportionally two resistance can be calculated as R1XR2/SUM OF R1+R2. many values can be calculated as a fraction 1/r+1/r2+1/3 ....and take the total sum reciprocal
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
When one load is removed from a parallel circuit the total resistance decreases?
No, the total resistance increases.
Two resistors of 400 Ohm and 600 Ohm are in parallel What is the equivalent resistance?
Use the general equation for resistance in parallel: 1/R = 1/R1 + 1/R2
What is the ratio of equivalent resistance of series and parallel combination of n equal resistance to the equivalent resistance on parallel combination?
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.
A piece of copper wire was cut into n equal parts these parts are connected in parallel how will the resistance of the parallel combination compare with the resistance of the wire?
The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared.
Determine and draw the equivalent resistances when 1 ohm in parallel with 2 ohm?
The equivalent resistance of the parallel combination is 2/3 ohm.
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 is resistivity connected to resistance?
Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
Does the current split in parallel circuits affect the overall resistance in the circuit?
Yes, the current split in parallel circuits does affect the overall resistance in the circuit. In a parallel circuit, the total resistance decreases as more branches are added because the current has multiple paths to flow through, reducing the overall resistance.
What is law of combination of resistors?
The resistance of two or more resistors in series is the sum of their resistances. RS = sumI=1,N (RI) The resistance of two or more resistors in parallel is the inverse of the sum of the inverses of the resistances. This is the same as saying that the conductance of two or more resistors in parallel is the sum of their conductances. RP = 1 / sumI=1,N (1/RI)
When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?
When more light bulbs are added in parallel to a circuit, the total resistance of the circuit decreases. This is because in a parallel circuit, the reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances. More paths for current to flow mean less overall resistance in the circuit.
What is the purpose of resistance?
Resistance doesn't have a 'purpose'; it exists whether you want it or not. You can modify it by adding more resistance in series or in parallel, but you can't avoid it!
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What are the laws governing parallel circuit?
Well, this is a nice question. I will just try to answer it. Note that the combined resistance in parallel will always be less than any of the individual resistances. In the parallel system, there is a separate independent path from the source to each resistance and back to the source, therefore each has the same voltage drop. This means that the voltage must be the same at each point in the parallel circuits. There are three rules governing simple parallel circuits of resistive elements: 1. Voltage across each resistor is the same as the voltage across the parallel combination. 2. The current flowing through the parallel combination is the sum of the current in the separate branches. 3. Summing resistance of a parallel circuit can be stated as follows: The reciprocal of the total resistance is equal to the sum of the reciprocals of each of the individual resistances.
