F2 - SEM1 - Circuit - 8.5 Electrical Circuit Flashcards
What are the 2 major types of circuit connections?
Series circuits
Parallel circuits
What is a series circuit?
The current flows in a series circuit along one path only
How are the circuit components connected in series circuit?
Connected in series
What is the characteristics of current in a series circuit?
The current is the same at all points
What is the characteristics of voltage in a series circuit?
The sum of the voltage across each electrical appliance is equal to the voltage of the energy source
What is the disadvantage of a series circuit?
If a series circuit is broken at any point, the current will not flow in the circuit
What is a parallel circuit?
The current has more than one path to flow.
How are the electric components connected in a parallel circuit?
Connected in parallel
How do we call the paths in a parallel circuit?
Branches
What is the characteristics of current in a parallel circuit?
The current in the main loop = sum of the currents in the branches
The current flowing in the branch with higher resistance is smaller
What is the characteristic of voltage in a parallel circuit?
The voltage across each branch is the same
What happen if a parallel circuit is broken at any branch?
Current will still flow in other branches.
Order the bulbs in the brightness level from high to low and explain why
X —> Y —> Z
The resistance in PQ is low => current flow through PQ is higher => X is the brightest
Y and Z are in series => current flow through Y is higher than Z => Y is brighter than Z
What is the relationship between A1, A2 and A3?
A3 = A1 + A2
