A fresh alkaline zinc battery can have an open-circuit voltage of 1.6 volts, but an iron-disulfide battery with an open-circuit voltage below 1.7 volts is entirely discharged.
9 volts/ 3 amps = 3 ohms. A light bulb is connected to a 9-volt battery that causes 3 amps of current through the bulb, What is the resistance of the light bulb in the circuit shown.
