Circuits

Question 1

Series circuit

Answer 1

-current stays the same everywhere
-p.d is shared between components
-total resistance = sum of each components resistance

Question 2

Parallel circuit

Answer 2

-total current = sum of current in each branch
-p.d is equal across branches
-total resistance = less than the smallest resistance component

Question 3

Current

Answer 3

Flow of charge past a given point every second

Question 4

Charge equation

Answer 4

Charge (C) = current (A) x time (s)

Question 5

Potential difference (p.d)

Answer 5

Difference of electrical potential between two points

Question 6

P.d equation

Answer 6

P.d (V) = current (A) x resistance (ohms)
