How does a battery supply electrical energy to a circuit?
O A. Negatively charged particles that are concentrated at the negative
terminal are repelled from one another, forcing them into a
conducting wire.
B. Chemical reactions in a battery cause positively and negatively
charged particles to separate and become concentrated at the
battery terminals.
C. Chemical reactions in a battery cause positively and negatively
charged particles to concentrate in the center of the battery.
D. The force of attraction between positively and negatively charged
particles generates electrical energy within the battery,
