Enter the voltage and resistance into the calculator to determine the current. This calculator uses Ohm’s Law to evaluate the current flowing through a circuit.
Input Current Formula
The following formula is used to calculate the input current.
I = V / R
Variables:
- I is the current (amperes)
- V is the voltage (volts)
- R is the resistance (ohms)
To calculate the input current, divide the voltage by the resistance.
What is Input Current?
Input current refers to the electric current that flows into a circuit or electrical device. It is determined by the voltage applied to the circuit and the resistance of the circuit according to Ohm’s Law. The input current is a crucial parameter for ensuring that circuits operate within safe and efficient limits.
How to Calculate Input Current?
The following steps outline how to calculate the Input Current.
- First, determine the voltage (V) applied to the circuit in volts.
- Next, determine the resistance (R) of the circuit in ohms.
- Use the formula from above = I = V / R.
- Finally, calculate the Input Current (I) in amperes.
- After inserting the variables and calculating the result, check your answer with the calculator above.
