parallel circuits

Question 1

parallel circuit

Answer 1

each component is separately connected to the +ve and -ve of the supply

Question 2

which component is always connected in series?

Answer 2

ammeter

Question 3

what happens if you remove or disconnect a component?-parallel

Answer 3

it will hardly affect the others

Question 4

potential difference in parallel

Answer 4

it is the same across all components V₁=V₂…

Question 5

current in parallel

Answer 5

it is shared between branches
the total current flowing is equal to the total of all the currents through components
current going into a junction has to equal current leaving

Question 6

what is the current is two identical components are connected in parallel?

Answer 6

the same current will flow through each

Question 7

resistance in parallel

Answer 7

adding a resistor reduces the resistance

Question 8

why is resistance decreased with more resistors?-parallel

Answer 8

both resistors have same pd
pushing force making current flow is same as source pd for every resistor added
by adding another loop, the current has more than one direction to go in
increases total current that can flow around so resistance is decreased
