A filament bulb and a resistor are connected in series to a battery. Which of the following will contribute to the load of the circuit?

A. Bulb
B. resistor
C. Bulb and resistor
D. none

I'm thinking the resistor, but I'm unsure. Thanks

    C is the correct answer. Both have resistance to current (though the filament's resistance is most likely very small, compared to the resistor). Their combined resistance R1+R2, is the load.

    Ohhhhhhhhhh I understand, thank you for the help!
