That's correct! Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across the conductor and inversely proportional to the resistance (R) of the conductor. Mathematically, it can be expressed as:

I = V / R

To find the value of current using Ohm's Law, you need to know the values of voltage and resistance. Let me explain how you can use Ohm's Law to find the current (I) step by step:

1. Identify the known values: Determine the voltage (V) and resistance (R). Make sure to use the appropriate units (e.g., volts for voltage, ohms for resistance).

2. Substitute the values into the formula: Plug in the known values of voltage (V) and resistance (R) into the Ohm's Law equation: I = V / R.

3. Perform the calculation: Divide the voltage (V) by the resistance (R) to calculate the current (I).

For example, let's say you have a circuit with a voltage of 12 volts and a resistance of 3 ohms. To calculate the current flowing through the circuit, you would substitute these values into the formula:

I = 12 volts / 3 ohms

I = 4 amps

Therefore, in this example, the current flowing through the circuit would be 4 amperes.

Remember, Ohm's Law is a fundamental formula in electrical engineering and allows you to determine the relationship between current, voltage, and resistance in a circuit.
