A circuit has a source with an electrical potential of 12 V. The circuit contains one resistor.If a second resistor is added to the circuit in series, what effect will this have on the current in the circuit?
A)The current will increase.
B)The current will decrease.
C)The current will not be affected.
D)The current will switch from DC to AC.
