To calculate the current (in amperes) from the voltage (in volts), you use **Ohm's Law**, which states:
\[
I = \frac{V}{R}
\]
Where:
- **I** = Current (in amperes, A)
- **V** = Voltage (in volts, V)
- **R** = Resistance (in ohms, Ω)
So, to calculate the current, you need to know the voltage across the circuit and the resistance.
### Example:
If you have a voltage of 12V and a resistance of 6Ω, the current will be:
\[
I = \frac{12V}{6Ω} = 2A
\]
So, the current flowing in the circuit is 2 amperes.
\[
I = \frac{V}{R}
\]
Where:
- **I** = Current (in amperes, A)
- **V** = Voltage (in volts, V)
- **R** = Resistance (in ohms, Ω)
So, to calculate the current, you need to know the voltage across the circuit and the resistance.
