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 same current flows through each component.

What happens to the current in a series circuit?

Back

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

Front

What happens if one component in a series circuit fails?

Back

If one component fails (like a light bulb), the entire circuit is broken and all components stop working.

Front

What is a parallel circuit?

Back

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

What happens to the current in a parallel circuit?

Back

In a parallel circuit, the total current is divided among the different paths, and each component receives the same voltage.

Front

What happens if one component in a parallel circuit fails?

Back

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

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.

Front

How does increasing resistance affect current?

Back

As resistance increases, the current decreases, assuming voltage remains constant.

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). It can be expressed as V = I * R.

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

Back

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