Intro to Circuits Review - Parallel and Series

Front

What is a series circuit?

Back

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

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, all the bulbs will go out because the circuit is broken.

Front

What is a parallel circuit?

Back

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

Front

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

Back

If one bulb in a parallel circuit burns out, the other bulbs will remain lit because the circuit is not broken.

Front

What is the main advantage of using a parallel circuit?

Back

The main advantage of a parallel circuit is that if one component fails, it does not affect the operation of other components.

Front

In a parallel circuit, how does the voltage across each component compare?

Back

In a parallel circuit, the voltage across each component is the same.

Front

In a series circuit, how does the current behave?

Back

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

Front

What is the total resistance in a series circuit?

Back

The total resistance in a series circuit is the sum of the individual resistances of all components.

Front

What is the total resistance in a parallel circuit?

Back

The total resistance in a parallel circuit is less than the smallest individual resistance and can be calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R): V = I * R.
