How do you find the minimum value of a resistor?

How do you find the minimum value of a resistor?

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 the minimum and maximum value of resistance?

Maximum and minimum resistance is 9 and 1 ohm respectively. All resistor are of same resistance , R = 3 ohm. We know, equivalent resistance is maximum when all resistance are in series. Therefore, maximum resistance , Also, equivalent resistance is minimum when all resistance are in parallel.

How do you find minimum and maximum currents?

Use V/R to get I, and min I = V/ max R.

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 color is a 330 ohm resistor?

Band Value
2nd Orange 3
3rd Brown 10
4th gold +-5%
330 Ohm tolerance: +-5%

What is minimum effective resistance?

Minimum effective resistance will be when all the resistors are in parallel combination. So, Reffmin​​=R/n.

What is minimum load?

The minimum load is the minimum current or power that must be drawn from the power supply in order for the supply to meet its performance specifications. It refers to the amount of load required for a particular power supply to operate reliably, and it is usually a function of the output voltage.

How do you find the minimum current?

Use the formula for power: Power = Voltage x Current, or P = VI. If you are trying to calculate the minimum load and you happen to only know the power and voltage ratings of your power supply, you can use the formula P = V2/R, which can become R = V2/P.

How do you calculate resistance value?

Divide the voltage by the current to get your resistance. This formula, known as Ohm’s Law, is a fundamental law of electronics and states that the voltage is equal to the resistance multiplied by the current. For example, a 120 volt circuit that generates 10 amperes of current would have a resistance of 12 ohms.
