1. A battery with a capacity of 2500 mAh (milliamp-hours) is used to power a device that constantly draws 400 mA of current. Assuming that the battery is ideal, how long will the battery last? The same battery as above is now used to power a clock that only draws current when the second hand "ticks". The current draw during this movement is 2mA. A clock ticks every second but note that the second hand doesn't take a second to...

A student is provided with a 12.0-V battery of negligible internal resistance and four resistors with the following resistances: 100 Ohms, 30 Ohms, 20 Ohms, and 10 Ohms. The student also has plenty of wire of negligible resistance available to make connections as desired. 1. Using all of these components, draw a circuit diagram in which each resistor has nonzero current flowing through it, but in which the current from the battery is as small as possible. 2. Using all...
