What is the formula of 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 is minimum and maximum resistance?
Maximum resistance can be obtained when the resistance are connected in series and minimum resistance can be obtained when the resistances are connected in parallel.
What is maximum effective resistance?
Maximum effective resistance is total possible resistance of the circuit (series combination is used to increase resistance) Minimum effective resistance is the least possible resistance of the circuit (parallel combination is used to decrease resistance)
How to calculate the resistance of a circuit?
1. Say you have a nominal 22Ω resistor with 5% tolerance. 2. The actual resistor value could be as low as 22Ω – 5% of 22Ω 3. Or the actual resistor value could be as high as 22Ω + 5% of 22Ω 4. Do the calculation to find that 5% of 22Ω is 1.1Ω 5. The actual resistor value could be as low as 22Ω – 1.1Ω = 20.9Ω
How is the thermal resistance of an IC package determined?
The thermal resistance of an IC package is the measure of the package’s ability to transfer heat generated by the IC (die) to the circuit board or the ambient. Given the temperatures at two points, the amount of heat flow from one point to the other is completely determined by the thermal resistance.
What is the tolerance of a 5% resistor?
The last band tells you about the tolerance of the resistor value. A 5% resistor will have a value that is within a 5% limit of its nominal value. I think axedrytouch3 wants to know how to work out the range of values a resistor might have given its nominal value and tolerance. 1. Say you have a nominal 22Ω resistor with 5% tolerance.
Which is the source resistance that maximizes power transfer?
In fact, the source resistance that maximizes power transfer is always zero, regardless of the value of the load resistance. The theorem can be extended to alternating current circuits that include reactance, and states that maximum power transfer occurs when the load impedance is equal to the complex conjugate of the source impedance.
