Electrical Circuits Quiz

What happens to the current in a series circuit?

• It is divided among each component

• It remains constant across all components

• It increases in each component

• It decreases in each component

How is voltage distributed in a parallel circuit?

• It is divided among the branches

• It remains the same in all branches

• It increases in each branch

• It decreases as it passes through each branch

In a mixed circuit, how are components connected?

• All in series

• All in parallel

• Some in series and others in parallel

• Each component has its own independent path

What is an advantage of a parallel circuit over a series circuit?

• It is easier to build

• If one component fails, the others keep working

• Voltage increases in all components

• Current remains constant throughout the circuit

What happens if a resistor burns out in a series circuit?

• The entire circuit stops working

• Current is divided among the remaining components

• Voltage increases in the remaining components

• The other components keep working
