When a single high-resistance bulb is connected

Reference no: EM13544662

When a single high-resistance (long) bulb is connected to a 1.5 volt battery, the current through the battery is about 80 milliampere. If you add another high-resistance (long) bulb in parallel, the battery current of course increases to 160 milliampere. Select all of the true statements given this situation. 1.The battery is ohmic. 2.The battery is not ohmic. 3.Current through the battery is proportional to ?V across the battery. 4.Current through the battery is not proportional to ?V across the battery. 5.The battery always puts out the same current.
