Question
A $1.5 \mathrm{V}$ flashlight battery can maintain a current of 0.30 A for $4.0 \mathrm{h}$ before it is exhausted. How muchchemical energy is converted to electrical energy in this process? (Assume zero internal resistance of the battery.)
Step 1
We can do this using the formula: Q = I * t where Q is the charge, I is the current, and t is the time. Q = (0.30 A) * (4.0 h * 3600 s/h) = 4320 C Show more…

A $1.5-\mathrm{V}$ flashlight battery can maintain a current of $0.30 \mathrm{A}$ for $4.0 \mathrm{h}$ before it is exhausted. How much chemical energy is converted to electrical energy in this process? (Assume zero internal resistance of the battery.)
A flashlight uses batteries that add up to 4.5 V and has a power output of 0.44 W. (a) How much current is drawn from the batteries? A (b) What is the effective resistance of the flashlight? Ω
A 1.5 V D-size battery stores $54 \mathrm{kJ}$ of energy. What steady current could this battery provide for 20 h before being depleted?
