**how to calculate current when given voltage and resistance**

To calculate voltage, V: put your finger over V, this leaves P over I, so the equation is V = P / I The amp is quite large for electronics so we often measure current in milliamps (mA) and power in milliwatts (mW).... The law stating that the direct current flowing in a conductor is directly proportional to the potential difference between its ends. It is usually formulated as V = IR, where V is the potential difference, or voltage, I is the current, and R is the resistance of the conductor.

**Resistance Wattage? Physics Forums**

This course emphasizes the use of simple tools; the Ohm's Law Triangles and the Ohm's Law Wheel, to accurately calculate any of the characteristics such as voltage, current, resistance or power in an electrical or electronic circuit.... It is also possible to convert watts to amps if the resistance of the circuit is known using the formula: amps = v(watts ? ohms) It is not possible to convert watts directly to amps without also knowing voltage or resistance.

**How many Amps in a Volt? Volts to Amps Calculator and**

This course emphasizes the use of simple tools; the Ohm's Law Triangles and the Ohm's Law Wheel, to accurately calculate any of the characteristics such as voltage, current, resistance or power in an electrical or electronic circuit.... To calculate amps, divide the voltage by the resistance in ohms. Current (A) = Voltage (V) ? Resistance (?) For example, let’s find the current of a 12 volt circuit with 10 ohms of resistance.

## How To Find Resistance With Voltage And Watts

### 3/10/2013 · Find out why Close. Resistors (2 of 11) in Parallel, Calculating Voltage, Resistance and Current Step-by-Step Science Calculating Voltage, Resistance and Current …

- The relationship between wattage, voltage and frequency is governed by circuit impedance. The impedance is a complex form of resistance. It's a combination of regular resistance …
- A motor requires 36 volts and uses 40 watts of power. 36 volts squared, then divided by 40 watts has a total resistance of 32.4 ohms. 36?/40 = 1296/40 = 32.4 There are 1.5 volts running through a component using 2 watts.
- 6/04/2011 · If an appliance is rated at 5 amps and 120 volts, the wattage is 600 watts (5 amps times 120 volts, which equals 600 watts). Step 5: Use current and resistance …
- 29/01/2007 · Best Answer: The resistor value is not given in kilowatts, it is given in ohms. The watt rating on a resistor is used to determine the amount of power that the resistor can safely handle. This power is equal to P=V^2/R=I^2*R, where V is voltage, I is current, and R is resistance (in ohms). To determine
