The formula to calculate the milli-amps (ma) from volts is:
\[ ma = \frac{P}{V} \times 1000 \]
Where:
Volts are a measure of voltage and ma stands for milli-amps, which is a measure of current. These two are related through the equation \( P = I \times V \), where \( P \) is power, \( I \) is current, and \( V \) is voltage. To calculate milli-amps from volts, divide the power by the voltage, then multiply by 1000.
Example 1:
Calculation:
\[ ma = \frac{10}{5} \times 1000 = 2000 \text{ mA} \]
Example 2:
Calculation:
\[ ma = \frac{15}{3} \times 1000 = 5000 \text{ mA} \]
