What is a parallel circuit? begynn å lære
|
|
A circuit with more than one branch/path for current to flow through
|
|
|
What happens to the current in a parallel circuit? begynn å lære
|
|
The current splits between the branches
|
|
|
What rule applies at a junction? begynn å lære
|
|
Total current = total current leaving.
|
|
|
What is the equation for current in parallel circuits? begynn å lære
|
|
|
|
|
What happens to voltage in a parallel circuit? begynn å lære
|
|
Voltage is the same across every branch
|
|
|
What is the voltage rule for parallel circuit begynn å lære
|
|
|
|
|
If a battery is 6v, how much voltage does each branch receive in parallel? begynn å lære
|
|
|
|
|
What happens when one bulb breaks in a parallel circuit? begynn å lære
|
|
|
|
|
Why do bulbs stay bright in parallel? begynn å lære
|
|
Each bulb receives the full battery voltage.
|
|
|
What happens to the total resistance when more branches are added? begynn å lære
|
|
Total resistance decreases.
|
|
|
Why does resistance decrease in parallel circuits? begynn å lære
|
|
Because there are more paths for charge to flow
|
|
|
What happens to the total current when resistance decreases? begynn å lære
|
|
|
|
|
Which equation links voltage, current, resistance? begynn å lære
|
|
|
|
|
Why are household circuits connected in parallel? begynn å lære
|
|
So appliances work independently and each gets full voltage.
|
|
|
What happens to current in a branch with higher resistance? begynn å lære
|
|
Less current flows through it.
|
|
|
What device measures current? begynn å lære
|
|
|
|
|
How is an ammeter connected? begynn å lære
|
|
|
|
|
What device measures voltage? begynn å lære
|
|
|
|
|
How is a voltmeter connected? begynn å lære
|
|
In parallel across a component.
|
|
|
What are the advantages of parallel circuits? begynn å lære
|
|
Components work independently / full voltage across each branch / one broken component doesn’t stop the others
|
|
|
What are the disadvantages of parallel circuits? begynn å lære
|
|
More wiring needed / More complicated / battery drains fast
|
|
|
In series or parallel circuits is current the same everywhere? begynn å lære
|
|
|
|
|
In series or parallel circuits is voltage the same across components? begynn å lære
|
|
|
|
|
What is a common exam mistake with parallel circuits? begynn å lære
|
|
Saying voltage splits between branches
|
