How many electrons are involved in the process? * The voltage source of this current is 12 Volts. What is the power produced by the source?
Which of the following statement is false regarding the emf?
O a. The battery or other emf source always produces the same amount of current regardless of the kind of component/s in the circuit.
O b. For a real source of emf, the terminal voltage equals the emf only if no current is flowing through the source.
O c. The source of emf supplies a constant potential difference independent of the current in series with an internal resistance.
O d. The increase in internal resistance may decrease the terminal voltage.
O e. The battery may overheat due to the increased power dissipated by the internal resistance.
