What is the minimum value of resistance?
The correct answer is 1.25 Ohm. So, minimum resistance (R) = 1.25 Ohm.
How do you find the minimum resistance?
While equivalent resistance increases when resistors are joined in series e.g., Req = R₁ + R₂ + R₃ + …. + Rn. 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 .
What are resistance values?
The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.
What is maximum and minimum tolerance?
The nominal value is the average of the minimum and the maximum allowed values. The tolerance is half the difference between the maximum and the minimum. So, if a resisters can range from 90 to 110 ohms, its nominal value is 100 ohms. Its tolerance is 10 ohms, which happens to be 10% of the nominal value.
What is the minimum resistance which can be made using 1/5 ohm?
For 5 resistors each of 1/5 ohms, the equivalent resistance is given by : So, the minimum resistance which can be made using five resistors is 0.04 ohms.
Is 51000 ohms a standard value for a 5% resistor?
51 k is a standard value.
What is the minimum resistance which using 5 resistors each of 1 2 ohm a 1/10 Ohm B 1 25 Ohm C 10 ohm D 2 ohm?
Minimum resistance is obtained in parallel combination. Thus, Rp=(1/5Ω)5=(1/25)Ω.
How do you find the maximum and minimum resistance?
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). The highest possible value is 517 K. The lowest possible value is 423 K.
What is a high resistance?
Resistance measurements are normally taken to indicate the condition of a component or a circuit. The higher the resistance, the lower the current flow. If abnormally high, one possible cause (among many) could be damaged conductors due to burning or corrosion.
How do you find the maximum resistance?
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). The highest possible value is 517 K.
How do you find maximum resistance?
i) To get the maximum resistance, the resistors should be in a series combination. ii) To get the minimum resistance, the resistors should have a parallel combination.
How do you find the minimum and maximum resistance values?
To calculate the minimum and maximum resistance values, we multiply the resistance value by the tolerance percentage to come up with the following values: Minimum = 750000 – (750000 x 5/100) = 750000 – 37500 = 712500 = 712.5kΩ Maximum = 750000 + (750000 x 5/100) = 750000 + 37500 = 787500 = 787.5kΩ
How much resistance tolerance do you need?
That said, you can express tolerance as a percentage of its preferred or nominal value. You should expect a tolerance range of 1 to 10percent—if you’re dealing with film resistors. But if you’re handling carbon resistors, you should expect tolerance of up to 20%.
What is the Max and Min resistance of gold?
Max Resistance = 22+1.1 and Min Resistance = 22-1.1 2) 6.8 kilo ohms = blue grey red gold. Gold has a tolerance of 5%. So 6.8k x (5/100) = 340. Max Resistance = 6.8k + 340. and so on… This question reminded me of a few subtleties associated with the notion of tolerance.
How do you find the tolerance value of a resistor?
The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value. 1kΩ or 1000Ω + 20% = 1,200Ω.
