What happens if you double the number of batteries used in a circuit? (Assume all of the batteries are the same.)

A.The current doubles only.
B.The voltage doubles only.
C.The current decreases.
D.The voltage decreases.
E.The voltage and current doubles.

Respuesta :

I think it is E. The voltage and current doubles. 

Answer;

E.The voltage and current doubles.

Explanation;

  • From the Ohm's law, current through a conductor is directly proportional to the potential difference at constant temperature and pressure.
  • Mathematically; I =V/R, where R is the resistance, I is the current and V is the voltage or the potential difference.
  • Current is directly proportional to the voltage, thus and increase in voltage  causes an increases in the amount of current in a circuit and vice versa.
  • Thus, if you double the number of batteries used in a circuit the both the current and voltage doubles.
