I measure a voltage drop of 30mv over a 2.5 ohm resistor. How long will a 3Ah battery last? Write your ansser 'XXX hours'
## Calculating Battery Life Here's how to calculate the battery life: **1. Calculate the current:** Using Ohm's Law (V = IR), we can calculate the current flowing through the resistor:
1 | I = V / R = 30 mV / 2.5 ohms = 0.012 A |
1 | Battery life = Battery capacity / Current draw = 3 Ah / 0.012 A = 250 hours |

Ohm's Law states that $V=IR$, where: * $V$ is the voltage in volts. * $I$ is the current in amperes. * $R$ is the resistance in ohms. Hence the current flowing through the resistor is $I=V/R=30\text{ mV}/2.5\text{ }\Omega=12\text{ mA}$. The battery capacity is the amount of charge it can store, measured in ampere-hours (Ah). It tells you how long the battery can supply a certain current before it is depleted. To calculate the battery life, we use the following formula: $Battery\ life = \frac{Battery\ capacity}{Current\ draw}$ In this case, the battery capacity is 3Ah and the current draw is 12mA, which is 0.012A. Therefore, the battery life is: $Battery\ life = \frac{3Ah}{0.012A} = 250 hours$ Therefore, the answer is '***250 hours***'
