What is a 2k resistor?

2k Resistor colour Code calculations are: 1st band= Red= 2 (1st digit) 2nd band= Black= 0 (2nd digit) 3rd band= Red= 100 (multiplier) 4th band= Gold= ±5\% (tolerance)

How do you determine the power rating of a resistor?

Resistor Power (P)

  1. [ P = V x I ] Power = Volts x Amps.
  2. [ P = I2 x R ] Power = Current2 x Ohms.
  3. [ P = V2 ÷ R ] Power = Volts2 ÷ Ohms.

How many watts is 2 ohms?

Example. Calculate the resistance in ohms of a resistor when the voltage is 5 volts and the power is 2 watts. The resistance R is equal to square of 5 volts divided by 2 watts, which is equal to 12.5 ohms.

What color is a 2K ohm resistor?

2K Ohm Resistor Color Code: Red, Black, Red, Golden. Resistance: 2K Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 11.18mA .

What’s the difference between K ohms and ohms?

One kiloohm is equal to 1,000 ohms, which is the resistance between two points of a conductor with one ampere of current at one volt. The kiloohm is a multiple of the ohm, which is the SI derived unit for electrical resistance.

How do you calculate the power rating?

Calculate power rating in KVA when you know voltage and output resistance. Use the formula: P(KVA) = (V^2/R)/1000 where R is resistance in ohms. For example, if V is 120 volts and R is 50 ohms, P(KVA) = V^2/R/1000 = (14400/50)/1000 = 288/1000 = 0.288 KVA.

What is power resistance rating?

The power rating of a resistor is the specification given with a resistor that serves to tell the maximum amount of power that the resistor can withstand. Thus, if a resistor has a power rating of 1/4 watts, 1/4 watts is the maximum amount of power that should be fed into the resistor.

How do you calculate watts to Ohms?

Watts, Volts, Amps & Ohms Calculator

  1. Watt calculation/conversion formulas: watts = volts² / ohms. watts = amps² * ohms.
  2. Volt calculation/conversion formulas: volts = √ watts * ohms. volts = watts / amps.
  3. Amp calculation/conversion formulas: amps = volts / ohms.
  4. Ohms calculation/conversion formulas: ohms = volts / amps.
