## What is the formula for power in current?

P = R × I2 or V2/ R: These formulas are a variant of ohm’s law. Here R stands for resistance, V stands for potential difference and I stands for current. It states that power is directly proportional to the square of potential difference and inversely proportional to the resistance offered by the conductor.

**What is the relationship between current voltage and power?**

A volt is a derived unit for electric potential, electromotive force, and electric potential difference. The relation between watt and volt is direct….AC and DC.

Current Type | Formula | Terms |
---|---|---|

AC | PW= PF × VV × IA | IA is current in ampere |

DC | PW= VV × IA | PW is Power in watt |

VV is voltage in volts | ||

IA is current in ampere |

**How do you calculate kW from volts and amps?**

To convert amps to kilowatts the power formula can be used, which states that I = P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts, divided by 1,000.

### How do I convert kW to current?

AC three phase kilowatts to amps calculation formula

- I = 1000 × P / (√3 × PF × VL-L )
- amps = 1000 × kilowatts / (√3 × PF × volts)
- A = 1000 × kW / (√3 × PF × V)
- I = 1000 × 0.33kW / (√3 × 0.8 × 110V) = 2.165A.

**What is the formula for volts?**

When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.

**What is the relationship between power, voltage and current?**

Current is the time rate of flow of charges in a circuit

## How do you calculate voltage and current?

Voltage (V) = Current (I) * Resistance (R) Power (P) = Voltage (V) * Current (I) Enter any two known values and press “Calculate” to solve for the others.

**What is the formula to calculate power?**

– BHP = (Torque × RPM )/5252,where torque is lb -ft and n = revolution per min. – BHP = BP /33000,where BP (in watt ) = Torque×2π×RPM (RPM in min. ) Where torque in the formula of BP is in lb -ft. – BHP =BP (in Watt ) / 746 we get it in horse power ,since 1 HP = 746 watt.

**How to convert amps to KVA?**

Single phase kVA to amps calculation formula
