Circuits Part 2 Flashcards
What are the two basic types of circuits?
Series Circuits and Parallel Circuits
What is a series circuit?
A circuit in which electric charges have only one possible pathway to travel from the negative terminal of the battery to the positive terminal.
In a series circuit, how does the current behave?
The amount of current is the same in all parts of the series.
What happens to the resistance when resistors are added in series?
Adding resistors in series increases the resistance of the whole circuit.
What is the effect of adding a second bulb in a series circuit?
Both bulbs become dimmer.
In a series circuit with a 9V battery and two bulbs, what is the voltage across each bulb?
4.5V for each bulb.
What occurs if one light in a series circuit burns out?
The entire circuit is interrupted, and all lights go out.
What is a parallel circuit?
A circuit in which electric charges have more than one possible pathway to travel from the negative terminal of the battery to the positive terminal.
How does current behave in a parallel circuit at a junction?
When the circuit is split at the junction, the current decreases.
What happens to the current when junctions converge in a parallel circuit?
The current increases.
Does adding more resistors in parallel affect the resistance in other pathways?
No, it does not affect the resistance in any other pathway.
What can be said about the potential difference across loads in a parallel circuit?
Each load receives the same potential difference supplied by the battery.
Fill in the blank: A schematic diagram is a _______.
[visual representation of an electrical circuit]
What are junctions in a parallel circuit?
Points where the circuit divides and combines.
What is the role of circuit symbols?
They serve as a universal language to communicate the different parts of the circuit.
True or False: In a parallel circuit, an interruption in one pathway affects all other pathways.
False
What is the first step in drawing schematic diagrams?
Ensure diagrams are neat and tidy.
What tools should be used when drawing circuits?
A ruler for straight lines and correct symbols.
