When the voltage sources are connected in the same polarity in series, they
A
produce a higher current
B
are additive and result in a higher total electromotive force
C
are subtractive and result in a lower total electromotive
force

A
B
C
D
V = emf + I r , where r is the internal resistance and I is
the current flowing at the time of the measurement
−
emf
, where r is the internal resistance and I is the
current flowing at the time of the measurement
V =
Ir
emf
, where r is the internal resistance and I is the
Ir
current flowing at the time of the measurement
V =
V = emf − I r , where r is the internal resistance and I is
the current flowing at the time of the measurement
