How does current flow through a series circuit made up of a cell and two bulbs - ANS-
Current comes out of the + end of the cell, down the wire, back into the - end of the cell
How are the components ordered in a series circuit? - ANS- Components one after the
other
What is the difference between a parallel and a series circuit? - ANS- Identical
components but the wiring is different
How does current flow through a parallel circuit made up of a cell and two bulbs? (use
version 1) - ANS- Current comes out of the + end of the cell, some current goes through
the start of one path through the top bulb, the rest goes downwards through the second
path through the bottom bulb, both rejoin at the point where the first path ends, it travels
back to the - end of the cell
(Open diagram) Explain the options the charges have - ANS- Charges arriving at the start
of the first path (A) have two options to get to end of the second path (B)
Either through top/bottom bulb
What are the paths like in parallel circuits? - ANS- They have more than one path
What is the name for the paths of circuits? - ANS- Branches
Top path = branch 1
Bottom path = branch 2
How does current flow through version 2 of the parallel circuit? - ANS- Current comes
out of the + end of the cell, it comes to a split into two paths, some current goes through
one path through the top bulb, the rest goes downwards through the second path
through the bottom bulb, both rejoin at the point where both paths end, it travels back to
the - end of cell
What can the + or - end of the cell also be known as? - ANS- + or - terminal
What happens when a resistor is added to a parallel circuit (with box-like branches) -
ANS- It makes a series section and a parallel section
It is composed of a resistor in series with two bulbs which are in parallel
We measure the current _______ a component - ANS- through
