Series and Parallel Circuits - Again

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the same current flows through each component.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which components are connected across common points or junctions, allowing multiple paths for current to flow.

How does the brightness of bulbs in a series circuit compare to those in a parallel circuit?

Back

In a series circuit, the brightness of bulbs decreases as more bulbs are added, while in a parallel circuit, each bulb receives the full voltage and can shine brighter.

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance in a series circuit increases as more resistors are added.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance in a parallel circuit decreases as more resistors are added.

Front

What is the formula for calculating total resistance in a series circuit?

Back

The total resistance (R_total) in a series circuit is the sum of the individual resistances: R_total = R1 + R2 + R3 + ...

Front

What is the formula for calculating 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

How does current behave in a series circuit?

Back

In a series circuit, the current is the same through all components.

Front

How does current behave in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents through each parallel branch.

Front

What is the effect of adding more batteries in series on the voltage supplied to a circuit?

Back

Adding more batteries in series increases the total voltage supplied to the circuit.
