What is 0.43 ohms in watts?

It's important to understand that ohms (Ω) and watts (W) are two different units of measurement. Ohms measure resistance, which is the opposition to the flow of electrical current. Watts measure power, which is the rate at which energy is transferred or used.

You cannot directly convert ohms to watts. To calculate power in watts, you need additional information, namely the voltage (V) across the resistor.

Here's the formula to calculate power using ohms and volts:

P = V²/R


  • P is power in watts (W)
  • V is voltage in volts (V)
  • R is resistance in ohms (Ω)


Let's say you have a resistor with a resistance of 0.43 ohms and it is connected to a 12-volt battery. To calculate the power dissipated by the resistor, we can use the formula:

P = 12² / 0.43

P ≈ 334.88 watts

Therefore, a resistor with a resistance of 0.43 ohms connected to a 12-volt battery will dissipate approximately 334.88 watts of power.

Important Note:

  • Power calculations are crucial for understanding the electrical characteristics of circuits.
  • The power dissipated by a resistor can cause it to heat up.
  • It is important to choose resistors with a wattage rating that is sufficient to handle the power they will be dissipating.

By understanding the relationship between ohms, volts, and watts, you can accurately calculate the power dissipation in a circuit and ensure the safety and proper functioning of your electrical components.
