## What is the formula for Watts law?

Watt’s Law states that: Power (in Watts) = Voltage (in Volts) x Current (in Amps) P = V I Combining with Ohm’s law we get two other useful forms: P = V*V / R and P = I*I*R Power is a measurement of the amount of work that can be done with the circuit, such as turning a motor or lighiting a light bulb.

### How do you calculate ohms law with amps?

Ohms Law and Power

- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

**What is the formula for voltage current and resistance?**

From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).

**What is the formula for AMP?**

Obtain Amps from Watts and Volts: The formula is (W)/(V) =(A). For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. This comes from the equation I = P / V. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

## How do you calculate amps to watts?

Converting amps to watts can be done using the power formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts. Thus, the power P in watts is equal to the current I in amps multiplied by the voltage V in volts.

### How many ohms does a 12 volt battery have?

The internal resistance of a 12-volts car battery is about 0.02 ohms.

**How do you calculate Ohm’s law?**

To students of electronics, Ohm’s Law (E = IR) is as fundamentally important as Einstein’s Relativity equation (E = mc²) is to physicists. When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.

**How do you find amps with voltage and resistance?**

The resistor’s current I in amps (A) is equal to the resistor’s voltage V in volts (V) divided by the resistance R in ohms (Ω): V is the voltage drop of the resistor, measured in Volts (V). In some cases Ohm’s law uses the letter E to represent voltage.

## How many amps are in a Volt?

1 ampere

A “volt” is a unit of electric potential, also known as electromotive force, and represents “the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt.” Stated another way, a potential of one volt appears …

### How do I calculate current amps?

Amps calculation with line to line voltage

- I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.
- amps = watts / (√3 × PF × volts) or.
- A = W / (√3 × PF × V) Example.
- I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

**Wie berechnet man eine Volt-Ampere zu einer Ampere?**

## Was ist der Unterschied zwischen einer Ampere und einer Voltampere?

Der Strom I in Ampere ist gleich der Scheinleistung S in Voltampere geteilt durch die Spannung V in Volt: Der Strom I in Ampere entspricht dem 1000-fachen der Scheinleistung S in Voltampere, geteilt durch die Quadratwurzel des 3-fachen der Spannung von Leitung zu Leitung V L-L in Volt:

### Was ist der Unterschied zwischen einem Ohm und einer Ampere?
