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'
To determine how long a 3Ah battery will last, we need to calculate the current flowing through the resistor and then use the battery's capacity to find the time. ### Step 1: Calculate the current (I) Using Ohm's Law: \[ I = \frac{V}{R} \] Where: - \( V = 30 \, \text{mV} = 0.03 \, \text{V} \) - \( R = 2.5 \, \Omega \) \[ I = \frac{0.03}{2.5} = 0.012 \, \text{A} \] ### Step 2: Calculate the time (T) The battery capacity is 3Ah (3 Ampere-hours). The time is given by: \[ T = \frac{\text{Battery Capacity}}{I} \] \[ T = \frac{3}{0.012} = 250 \, \text{hours} \] ### Final Answer: **250 hours**
Testing if the previous output matches the regex 250.{,10}hours: True
