A complete series circuit consists of a 12.0 V battery, a 4.70 O resistor, and a switch. The internal resistance of the battery
RoseWind [281]

With the switch open, there's no current in the circuit, and therefore
no voltage drop across any of the dissipative elements (the resistor
or the battery's internal impedance).  So the entire battery voltage
appears across the switch, and the voltmeter reads 12.0V .

A trcuk exerts 2700 N of force on a car that is stuck in the mud, and does not move. How much work has the truck performed? Show
Rasek [7]
I believe the correct answer would be zero. The work done in the truck is equal zero since the truck is not moving. Work by definition is the product of force and distance traveled due to the force. In this case, distance is zero giving us a zero work. Hope this helps.
