ma to Voltage Calculator:
Enter the values of current, I(mA) and resistance, R(Ω) to determine the value of Voltage, V(V).
ma to Voltage Formula:
Converting milliamperes to voltage is a common requirement in electrical engineering and electronics.
The voltage in a circuit can be determined using Ohm’s Law, which states that voltage (V) is the product of current (I) and resistance (R).
When the current is given in milliamperes, it must be converted to amperes by dividing by 1000. This conversion is essential for accurate calculations in circuits with small current values.
Voltage, V(V) in volts is calculated by dividing the current, I(mA) in milliamperes and resistance, R(Ω) in ohms by 1000.
Voltage, V(V) = I(mA) * R(Ω) / 1000
V(V) = voltage in volt, V.
I(mA) = current in milliamperes, mA.
R(Ω) = resistance in ohms, Ω.
ma to Voltage Calculation:
- Calculate the voltage for a current of 500 milliamperes and a resistance of 10 ohms:
Given: I(mA) = 500mA, R(Ω) = 10 Ω.
Voltage, V(V) = I(mA) * R(Ω) / 1000
V(V) = 500 * 10 / 1000
V(V) = 5V.
- Determine the current for a voltage of 5V and a resistance of 20 ohms:
Given: V(V) = 5V, R(Ω) = 20 Ω.
Voltage, V(V) = I(mA) * R(Ω) / 1000
I(mA) = V(V) * 1000 / R(Ω)
I(mA) = 5 * 1000 / 20
I(mA) = 250mA.
