- parallel circuits
- "separate connections"
- potential difference (P.D)
- EQUAL
- across each component
- all bulbs will be at the same brightness
- V1=V2=V3
- EQUAL
- current
- SHARED
- between branches
- A=A1+A2
- adds up
- 2 x 0.5A = 1A total (example)
- SHARED
- resistance
- TRICKY TO WORK OUT
- less than branch with smallest resistance
- circuit with 2 resistors in parallel
- lower resistance
- higher current
- total R < R total R < R2
- voltage
- charge only goes through one celll
- 2 x 12V = 12V total (example)
