Question: What Is Maximum Resistance?

What is a specific resistance?

Specific resistance is defined as the resistance offered per unit length and unit cross-sectional area when a known amount of voltage is applied..

What is the resistance between A and B in the given network?

In the given ciruit, the two 1 ohm resistors are connected in series. So, they can be replaced with a resistor of equivalent resistance. So, both the 1 ohm resistors can be replaced by a 2 ohm resistor. = 2/3 ohms.

What are the 3 types of tolerances?

Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances. Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances.

How do I calculate current?

Ohms Law and PowerTo find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

What is the effective resistance between A and B?

therefore the effective resistance between A and B is 10Ω

How is color code resistance calculated?

Calculating Resistor Values For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

What is the maximum resistance which can be made by using five resistors of 1/4 Ω?

The maximum resistance of five resistors is 1 ohm.

How should you connect the resistance to get the minimum resistance?

it Means, we can get minimum resistance when all the given resistors will join in parallel. And we can get maximum resistance when all the resistors will join in series . ∴ for finding minimum resistance , we have to join all resistors in parallel.

What is the effective resistance?

the resistance to an alternating current, expressed as the ratio of the power dissipated to the square of the effective current.

How do I calculate resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

What is the ratio of maximum to minimum resistance?

Hence, he ratio of the maximum to minimum resistance that can be obtained by combining them is n2.

How do you find the maximum and minimum tolerance?

Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1).

What is minimum effective resistance?

Minimum effective resistance will be when all the resistors are in parallel combination.

What is the resistance between A and B in the following circuit?

Equivalent resistance between A and B, RAB=(RAE+1)∥2=2∥2=1Ω

How is tolerance calculated?

TOLERANCE :Tolerance is the allowable variation for any given size in order to achieve a proper function. Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch.

What is nominal resistance?

Nominal resistance is determined by the common ratio shown right. ● Resistance coding Nominal resistance is expressed in 3 digits when the resistance tolerance is ±5% and in 4 digits when ±1%. The leading 2 or 3 digits indicate significant figure while the last digit indicates the number of zeros.

What is the maximum resistance?

Hence, the maximum resistance which can be made using five resistors each of 1/5 ohm is 1 ohm.
