What is a cell?
A device that provides electrical energy for a circuit.
How are cells connected in series?
Positive to negative — voltage adds up, current stays the same.
How are cells connected in parallel?
Positive to positive, negative to negative — current increases, voltage stays the same.
What happens if one bulb in a series circuit fails?
All bulbs go off.
What happens if one bulb in a parallel circuit fails?
Other bulbs stay on.
What is a logic gate?
An electronic switch used to control electrical signals.
What does an AND gate represent?
Both switches must be ON for the circuit to work (series).
What does an OR gate represent?
Either switch can be ON for the circuit to work (parallel).
What are logic gates found in
- Cellular phones
- Computers
- Laptops
In which direction does current flow?
From positive to negative.
What is conventional current flow
