Parallel Circuits

What is a key advantage of parallel circuits compared to series circuits?

• If one component fails, the entire circuit stops working.

• All components share the same current.

• If one component fails, other components still function.

• All components have different voltages.

Why do parallel circuits provide an advantage when a component fails?

• All components stop working to prevent damage.

• Other loops continue to function normally.

• Other components will not receive power.

• The circuit reroutes the current automatically.

In a parallel circuit with a 12 volt battery, what is the potential difference across each branch?

• 12 volts

• 6 volts

• Variable voltage depending on the component

• 24 volts

The total current of 4A flows in a two branch parallel circuit. Which of the following is possible?

• 1 amp in each loop

• 4 amps in each loop

• 2 amps in each loop

• 3 amps in one loop and 1 amp in the other

What analogy is used to explain current flow in parallel circuits?

• Water flowing through multiple pipes

• Light spreading from a source

• Heat spreading in a room

• Cars on a multi-lane highway

If a parallel circuit's loops have different resistances, how does the current distribute?

• More current flows through higher resistance

• No current flows through higher resistance

• Current is the same in all loops

• More current flows through lower resistance

What happens to the total resistance of a parallel circuit when more components are added?

• It remains the same

• It increases

• It decreases

• It becomes zero

What is the effect of adding more loops to a parallel circuit on its overall resistance?

• Increases the total resistance

• Decreases the total resistance

• No change in resistance

• Makes the circuit non-functional

A resistor is added in parallel with another resistor? Which of the following statements are true.

• The total resistance is greater than either of the individual resistors

• The total resistance remains unchanged

• The total current increases

• The total resistance is lower than either of the individual resistors

Two 10 Ohm resistors are added in parallel. The total resistance in the circuit is?

• Less than 10 Ohms

• 10 Ohms

• Greater than 10 Ohms

• Impossible to know
