Use data on battery characteristics to
estimate the useful lifetime of a D cell
driving a light bulb (assume 6 ohms).
Report the number of hours.
- Refer to battery data.
- Determine current flow through battery:
(1.5V)/(6 ohm) = 0.25 A = 250 mA
- Decide to use battery capacity of 8000 mAh as closest to operating conditions.
- Need h; have mAh and mA:
(8000 mAh)/(250 mAh) = 32 h -- seems high!
