Exploring Series and Parallel Circuits

What happens to a series circuit if one component fails?

• There is no effect on the circuit

• The circuit becomes a parallel circuit

• All components stop working

• Only the failing component stops working

How can you control individual lamps in a parallel circuit?

• By changing the lamp

• By breaking the circuit

• By using a resistor

• By using a switch

What is the effect of a broken component in a parallel circuit?

• All components will stop working

• Only the branch with the broken component is affected

• The circuit becomes a series circuit

• The voltage in the circuit increases

In a series circuit, how is the current affected by adding more components?

• It increases

• It decreases

• It remains the same

• It becomes zero

What happens to the current in a series circuit when a resistor is added?

• It remains unchanged

• It becomes zero

• It decreases

• It increases

What is the behavior of current in a parallel circuit with identical components?

• It stops

• It flows only through one branch

• It splits equally

• It decreases with more branches

In a parallel circuit, if the total current is 4 amps and there are two branches, how is the current distributed if the components are identical?

• 4 amps in each branch

• 3 amps in one and 1 amp in another

• 2 amps each branch

• 1 amp each branch

How is the potential difference distributed in a series circuit with two identical lamps?

• The lamps share the voltage unequally

• Each lamp gets half of the total voltage

• Each lamp gets the total voltage

• The voltage doubles

In a series circuit with a lamp and a resistor, if the total voltage is 6 volts, how might the voltage be distributed between them?

• 6 volts on the lamp only

• 6 volts on the resistor only

• 4 volts on the resistor and 2 volts on the lamp

• 3 volts each

What is the potential difference across each component in a parallel circuit if the cell has 6 volts?

• 3 volts each

• 6 volts each

• Variable depending on the component

• 12 volts each
