In a series current, each circuit has the same:
A. current
B. voltage
C. capacitance
D. resistance

If a resistor is added to a series circuit, the equivalent resistance:
A. increases
B. decreases
C. remains the same
D. becomes zero

    Now wait a minute - think
    If all your resistances are in series, then where is an electron to go after it passes through the first one? It can only go through the second one, then the third ......

    If you put yet another resistance in that poor electron's way, well what do you think happens to the overall resistance?

    so
    1-a
    2- b

    no. if you add resistance in a series circuit, the resistance has to increase.

  • physics - ,

    okay so it's A, A
