Series and Parallel Circuits - Again

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 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

How do you measure current in a circuit?

Back

To measure current, you connect an ammeter in series with the component whose current you want to measure.

Front

How do you measure voltage in a circuit?

Back

To measure voltage, you connect a voltmeter in parallel with the component whose voltage you want to measure.

Front

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit is broken and all components stop working.

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 work because there are multiple paths for the current.

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: R_total = R1 + R2 + R3 + ...

Front

What is the total resistance in a parallel circuit?

Back

The total resistance in a parallel circuit 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.

Front

What is the role of a resistor in a circuit?

Back

A resistor is a component that resists the flow of electric current, creating a voltage drop and controlling the current in the circuit.
