Answer to Question #46299 in Physics for promise

Question

The term 'lost volts' refers to -----------

energy per coulomb dissipated in the external (load) resistance
terminal potential difference
energy per coulomb dissipated in the internal resistance of the source of emf
energy per coulomb wasted to heat up the connecting wires

Answer 1

Answer:
The term ‘lost volts’refers to the difference between the emf and the terminal voltage. The voltage
is not ‘lost’. It is the voltage acrossthe internal resistance of the battery, but ‘lost’ for use in the external
circuit. The internal resistance of the battery can be treated just like
another resistor in series in the circuit.
The term 'lost volts'refers to energy per coulomb dissipated in the internal resistance of the
source of emf.
