series circuits

V = IR

what happens when a component is removed or disconnected in series circuits?

circuit is broken !

what is potential difference like in series circuits?

• shared

  • PD in a series circuit add up to the source

  • Vt = V1 + V2….

what happens when an identical bulb is added into a series circuit?

• bulbs become dimmer

  • PD is shared equally

what is current like in series circuits?

• the same everywhere

  • same current through all components

what is the current determined by in a series circuit?

• total PD of cells and total resistance of circuit

• I = V/R

what is resistance like in series circuits?

• adds up

  • Rt = R1 + R2

what happens when a resistor is added in series circuits?

• total current reduces

  • current is the same everywhere

• total resistance increases

  • resistance adds up
