Q
What is electric current like?
A
Like water flowing through a pipe — it’s how much electricity is moving!
3
Q
What does voltage do in a circuit?
A
It pushes the electricity, like water pressure!
4
Q
What is resistance?
A
Something that slows electricity down, like a clog in a pipe.
5
Q
What do we call the rule that connects voltage, current, and resistance?
A
Ohm’s Law: V=I×R
6
Q
What is a series circuit?
A
One single path — if one part breaks, the whole thing stops.
7
Q
What is a parallel circuit?
A
Many paths — other parts still work even if one breaks.
8
Q
In a series circuit, what happens to the current?
A
It stays the same through every part.
9
Q
In a parallel circuit, what happens to the voltage?
A
It stays the same across every branch.
