question		réponse
What is a parallel circuit? commencer à apprendre		A circuit with more than one branch/path for current to flow through
What happens to the current in a parallel circuit? commencer à apprendre		The current splits between the branches
What rule applies at a junction? commencer à apprendre		Total current = total current leaving.
What is the equation for current in parallel circuits? commencer à apprendre		Itotal = I1+I2+I3
What happens to voltage in a parallel circuit? commencer à apprendre		Voltage is the same across every branch
What is the voltage rule for parallel circuit commencer à apprendre		Vtotal=V1=V2=V3
If a battery is 6v, how much voltage does each branch receive in parallel? commencer à apprendre		Each branch receives 6v
What happens when one bulb breaks in a parallel circuit? commencer à apprendre		The other bulb stay on
Why do bulbs stay bright in parallel? commencer à apprendre		Each bulb receives the full battery voltage.
What happens to the total resistance when more branches are added? commencer à apprendre		Total resistance decreases.
Why does resistance decrease in parallel circuits? commencer à apprendre		Because there are more paths for charge to flow
What happens to the total current when resistance decreases? commencer à apprendre		Total current increases
Which equation links voltage, current, resistance? commencer à apprendre		V=IxR
Why are household circuits connected in parallel? commencer à apprendre		So appliances work independently and each gets full voltage.
What happens to current in a branch with higher resistance? commencer à apprendre		Less current flows through it.
What device measures current? commencer à apprendre		An ammeter
How is an ammeter connected? commencer à apprendre		In series
What device measures voltage? commencer à apprendre		A voltmeter.
How is a voltmeter connected? commencer à apprendre		In parallel across a component.
What are the advantages of parallel circuits? commencer à apprendre		Components work independently / full voltage across each branch / one broken component doesn’t stop the others
What are the disadvantages of parallel circuits? commencer à apprendre		More wiring needed / More complicated / battery drains fast
In series or parallel circuits is current the same everywhere? commencer à apprendre		Series circuits only
In series or parallel circuits is voltage the same across components? commencer à apprendre		Parallel circuits only
What is a common exam mistake with parallel circuits? commencer à apprendre		Saying voltage splits between branches
