Series and Parallel Circuits

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

In a parallel circuit, what remains constant throughout the circuit?

Back

Voltage remains constant throughout a parallel circuit.

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

Back

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

Front

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

Back

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

Front

How does increasing resistance affect current in a circuit?

Back

As resistance increases, the current decreases, according to Ohm's Law.

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) of the conductor: I = V/R.

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 all 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 is given by: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Voltage (V) = Current (I) x Resistance (R), according to Ohm's Law.
