Series And Parallel Circuit Flashcards
2 ways a component can be in a circuit
Parallel and series
Voltage is also known as
Potential difference
How doe’s potential difference across two components vary in series and parallel circuits
In parallel the P.D across each component is the same
In series the P.D across each component is split up between the two
If 2 resistors are in parallel what can be said about their total resistance
It will be less than the smallest resistance of the two
If 2 resistors are attached in series what can be said about their total resistance
Their total resistance is the sum of the two individual resistances
Where must a voltmeter be placed in a circuit
In parallel to what it’s measuring
Equation relating P.D, energy transferred and Charge
P.D=E/Q
A volt is also known as
Joules per coulomb’s
What is an electrical current
The rate of flow of charge
Equation linking charge current and time
Q=I x T
What can be said about the value of current at any point in a single closed loop
Current is the same at all points in a closed loop
What 2 factors in a circuit does current depended on
P.D
Resistance
What equation used to calculate P.D is current and resistance are known
P.D=current x resistance
What is an ammeter and where should it be in circuit
It measures current and should be in series
What happens when current reaches a junction in a circuit
It is conserved. The total current remains the same but is split between each branch
