Parallel Circuits

Front

What is a parallel circuit?

Back

A parallel circuit is an electrical circuit that has multiple paths for current to flow. If one path is interrupted, current can still flow through the other paths.

How does current behave in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents through each path. Each component receives the same voltage.

Front

What happens if one component fails in a parallel circuit?

Back

If one component fails in a parallel circuit, the other components continue to operate normally.

Front

What is the main difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, and if one fails, the entire circuit stops working. In a parallel circuit, components are connected across common points, allowing for multiple paths.

Front

How do you calculate total resistance in a parallel circuit?

Back

The total resistance (R_total) in a parallel circuit can be calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the voltage across components in a parallel circuit?

Back

The voltage across each component in a parallel circuit is the same and equal to the source voltage.

Front

What is a branch in a parallel circuit?

Back

A branch in a parallel circuit refers to each individual path that current can take. Each branch can contain one or more components.

Front

How does adding more branches affect total resistance in a parallel circuit?

Back

Adding more branches in a parallel circuit decreases the total resistance, as there are more paths for current to flow.

Front

What is the role of a resistor in a parallel circuit?

Back

A resistor in a parallel circuit limits the current flowing through that branch, affecting the overall current distribution.

Front

Can a parallel circuit be used in household wiring?

Back

Yes, parallel circuits are commonly used in household wiring to ensure that appliances can operate independently.
