Solves Ohm’s law equations

Ohm’s law calculator solves the three equations that define Ohm’s law:

  • Voltage (V) = Current (I) * Resistance (R)

    This equation tells us that the voltage across a conductor is equal to the current flowing through it multiplied by the resistance of the conductor.

  • Current (I) = Voltage (V) / Resistance (R)

    This equation tells us that the current flowing through a conductor is equal to the voltage across it divided by the resistance of the conductor.

  • Resistance (R) = Voltage (V) / Current (I)

    This equation tells us that the resistance of a conductor is equal to the voltage across it divided by the current flowing through it.

  • Power (P) = Voltage (V) * Current (I)

    This equation calculates the power dissipated in a circuit.

The ohms law calculator can be used to solve any of these equations, given the other two values.

Finds voltage, current, resistance

The ohms law calculator can be used to find the voltage, current, or resistance in a circuit, given the other two values. To use the calculator, simply enter the known values into the appropriate fields and the calculator will automatically calculate the unknown value.

Example:

Let’s say we have a circuit with a voltage of 12 volts and a resistance of 10 ohms. We want to find the current flowing through the circuit.

To do this, we would enter 12 volts into the “Voltage” field and 10 ohms into the “Resistance” field. The calculator would then automatically calculate the current, which in this case is 1.2 amps.

The ohms law calculator can also be used to find the resistance or voltage in a circuit, given the other two values. Simply enter the known values into the appropriate fields and the calculator will automatically calculate the unknown value.

Here are some additional examples of how the ohms law calculator can be used:

  • To find the voltage drop across a resistor, given the current flowing through it and the resistance of the resistor.
  • To find the current flowing through a wire, given the voltage across it and the resistance of the wire.
  • To find the resistance of a conductor, given the voltage across it and the current flowing through it.
  • To find the power dissipated by a resistor, given the voltage across it and the current flowing through it.

The ohms law calculator is a valuable tool for anyone working with electrical circuits. It can save time and effort, and it can help to ensure that your calculations are accurate.

AC and DC circuits対応

Ohms law calculator can be used to solve problems involving both AC (alternating current) and DC (direct current) circuits.

  • AC circuits

    In AC circuits, the voltage and current flow in opposite directions at different times. The ohms law calculator can be used to find the voltage, current, and resistance in an AC circuit, just like it can in a DC circuit. However, it is important to note that the resistance in an AC circuit may be different from the resistance in a DC circuit. This is because AC circuits can contain inductive and capacitive components, which can affect the flow of current.

  • DC circuits

    In DC circuits, the voltage and current flow in the same direction at all times. The ohms law calculator can be used to find the voltage, current, and resistance in a DC circuit, just like it can in an AC circuit. However, it is important to note that the resistance in a DC circuit is constant, unlike the resistance in an AC circuit.

Whether you are working with AC or DC circuits, the ohms law calculator can be a valuable tool for solving problems and ensuring that your calculations are accurate.

Simple and easy to use

The ohms law calculator is designed to be simple and easy to use, even for those who are not familiar with electrical circuits. The calculator typically has a simple interface with three fields: one for voltage, one for current, and one for resistance. Simply enter the known values into the appropriate fields and the calculator will automatically calculate the unknown value.

Most ohms law calculators also have a number of features that make them even easier to use. For example, many calculators allow you to select the units of measurement that you want to use (e.g., volts, amps, ohms). Some calculators also have a built-in help function that can provide you with more information about how to use the calculator.

Here are some tips for using an ohms law calculator:

  • Make sure that you enter the values in the correct fields. The voltage should be entered in the “Voltage” field, the current should be entered in the “Current” field, and the resistance should be entered in the “Resistance” field.
  • Select the appropriate units of measurement. Most calculators allow you to choose between volts, amps, and ohms.
  • If you are not sure how to use the calculator, check the built-in help function. Many calculators have a help button that you can click to get more information about how to use the calculator.

With a little practice, you will be able to use an ohms law calculator quickly and easily to solve problems involving electrical circuits.

Here is an example of how to use an ohms law calculator to find the current flowing through a circuit:

  1. Enter the voltage (in volts) into the “Voltage” field.
  2. Enter the resistance (in ohms) into the “Resistance” field.
  3. Click the “Calculate” button.
  4. The calculator will display the current (in amps) in the “Current” field.
