10.2 Resistance

Card 1 of 21

Why is the current the same everywhere in a series circuit?

A

Charge is conserved and cannot be used up or stored.

B

The current halves.

C
  • The LDR's resistance rises.
  • The circuit current falls.
  • The output potential difference changes until the lamp switches on.
D

For resistors in series, Rtotal=R1+R2+…R_{\text{total}}=R_1+R_2+\dotsRtotal​=R1​+R2​+…, while a parallel combination has total resistance smaller than its smallest branch resistance.
