Milliampere (mA) to Voltage (V) Conversion
Voltage can be calculated using two primary methods: the Power Method and Ohmโs Law.
1. Power Method โก
To determine voltage when power and current are known, use the formula:
V = P / ISince current is given in milliamperes (mA), convert it to amperes (A) using:
I(A) = I(mA) / 1000Thus, the formula becomes:
V = P / (I(mA) / 1000)Where:
- V = Voltage in volts (V)
- P = Power in watts (W)
- I(mA) = Current in milliamperes (mA)
Key Insight:
This method is useful for power supplies and electrical devices with specified power ratings.
2. Ohmโs Law โก
When resistance is known, voltage can be calculated using Ohmโs Law:
V = I ร RWith current in milliamperes (mA), convert to amperes (A) as follows:
V = (I(mA) / 1000) ร RWhere:
- V = Voltage in volts (V)
- I(mA) = Current in milliamperes (mA)
- R = Resistance in ohms (ฮฉ)
๐ก Understanding Voltage
Voltage is the electrical potential difference between two points in a circuit. It is essential for the operation of electrical devices.
- Measured in volts (V)
- Drives current through a circuit
- Critical for circuit design and analysis
