Homework 8

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected alongside each other, so the current can split and flow through multiple paths. If one component fails, the others can still function.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end in a single path. If one component fails, the entire circuit is broken and all components stop functioning.

Front

What happens to the current in a parallel circuit?

Back

In a parallel circuit, the total current is divided among the parallel branches. Each branch receives the same voltage, but the current can vary depending on the resistance of each branch.

Front

What happens to the current in a series circuit?

Back

In a series circuit, the same current flows through all components. The total resistance is the sum of the individual resistances, which affects the overall current.

Front

How can you identify a parallel circuit in a diagram?

Back

A parallel circuit can be identified by the presence of multiple paths for current to flow. Look for branches that connect to the same two points.

Front

How can you identify a series circuit in a diagram?

Back

A series circuit can be identified by a single path for current to flow. Components are connected one after another without any branching.

Front

What is the effect of adding more resistors in a series circuit?

Back

Adding more resistors in a series circuit increases the total resistance, which decreases the overall current flowing through the circuit.

Front

What is the effect of adding more resistors in a parallel circuit?

Back

Adding more resistors in a parallel circuit decreases the total resistance, which increases the overall current flowing through the circuit.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of current in a circuit. When closed, it allows current to flow; when open, it stops the flow.

Front

What happens to the bulbs in a series circuit if one bulb burns out?

Back

If one bulb in a series circuit burns out, the circuit is broken, and all bulbs will go out.
