There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
No, a 2.2k ohm resistor and a 220 ohm resistor are not the same resistance. The "k" in 2.2k ohm stands for "kilo," which represents a multiplier of 1000. Therefore, a 2.2k ohm resistor is equivalent to 2200 ohms, while a 220 ohm resistor is simply 220 ohms. The difference in resistance values is a factor of 10 due to the kilo prefix.
P = IV Where: P = power in watts, I = Current, and V= Voltage Using ohms law: V = IR where V=Voltage, I = Current, and R= Resistance First solve for I, I = V/R, 12/30 = .4 Then use the power equation: P = .4*12 = 4.8 Watts
Ohms law states that V = I * R I = V/R R = V/I P = I*V Where V = Voltage, I=Current, R = Resistance and P = Power or Watt Watt is the amount of electricity flowing through a line which is (Voltage times Current in (Amperage) = Power or watts) To find the power dissipated by a resistor of 1000 ohms, we first find the current I. The voltage is given as 200volts. Therefore I = V/R = 200/1000 = 0.2Amps We said Power or Watt = I*V Therefore the Power or watts dissipated by a resistor of 1000 ohms will be P=I*V = 200*0.2 = 40 Watts
Power dissipated = I2R 0.022 x 1000 = 0.4 watts

Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.Power is the voltage across the resistor SQUARED divided by the resistance. If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.1 Watt equals 1 Volt times 1 Amp.

Resistors are rated in ohms for their resistance value and in watts for the power they are capable of handling. They are not rated in volts or current.
Ohm's Law: Current is voltage divided by resistance.100 volts divided by 10 ohms is 10 amperes.This is also 1000 watts (power is voltage times current), so do not try it unless you have a resistor, a power supply, and a setup that can handle the power load!
To find the minimum power rating of a resistor, you can use the formula ( P = I^2 \times R ). Given that the current ( I ) is 400 mA (or 0.4 A) and the resistance ( R ) is 100 ohms, the power is calculated as ( P = (0.4)^2 \times 100 = 16 ) watts. Therefore, the minimum power rating for the resistor should be at least 16 watts to handle the maximum current safely. It's advisable to choose a resistor with a higher rating for added safety and reliability.
Power = I2 R = (0.02)2 x (1,000) = 0.4 watt
P = I^2 x R] P = 0.2^2 x 100 P = 4 W
I don't know what the parallel circuit has to do with it. You've onlygiven me a resistor and the current through it.When 0.03A of current passes through a 1,000Ω resistor, the resistordissipates energy at the rate of 0.9 watt.
The formula for calculating the power dissipated in a resistor, known as the i2r power, is P I2 R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.
