Parallel Circuits

Front

What is a parallel circuit?

Back

A parallel circuit is an electrical circuit where multiple components are connected across the same voltage source, allowing current to flow through multiple paths.

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

Back

In a parallel circuit, if one bulb burns out, the other bulbs will continue to light up because each bulb has its own separate path for current.

Front

What is the effect of closing a switch in a parallel circuit?

Back

Closing a switch in a parallel circuit allows current to flow through that path, potentially lighting up the connected components.

Front

How can you determine which bulbs will light up in a parallel circuit?

Back

To determine which bulbs will light up, you need to know which switches are closed and the configuration of the circuit.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (breaking the circuit) or closing (completing the circuit) the path for current.

Front

If Switch 2 is closed in a circuit with multiple switches, what will happen?

Back

If Switch 2 is closed, only the components connected in that path will operate, depending on the circuit configuration.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across the same voltage source, allowing multiple paths for current.

Front

What is the significance of voltage in a parallel circuit?

Back

In a parallel circuit, all components receive the same voltage from the power source, which affects their brightness and functionality.

Front

How does the resistance in a parallel circuit affect the overall current?

Back

In a parallel circuit, the total resistance decreases as more branches are added, which increases the overall current drawn from the power source.

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current in a parallel circuit increases when more branches are added because each branch provides an additional path for current to flow.
