## 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.

Given: I(mA) = 500mA, R(Ω) = 10 Ω.

Voltage, V(V) = I(mA) * R(Ω) / 1000

V(V) = 500 * 10 / 1000

V(V) = 5V.

1. 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.

### Applications and Considerations:
