What is a series circuit?

• A series circuit is a circuit where the components are connected in a single path, so the current flows through each component in sequence.

• A series circuit is a circuit where the components are connected in parallel.

• A series circuit is a circuit where the components are connected in a random order.

• A series circuit is a circuit where the components are not connected.

In a series circuit, how does the current flow through the components?

• The current flows randomly through each component.

• The current flows sequentially through each component.

• The current flows simultaneously through each component.

• The current flows in reverse order through each component.

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

• Decreases

• Remains constant

• Increases

• Becomes negative

Define parallel circuit.

• A circuit in which the components are connected in series, and the voltage is the same across each component but the current is different

• A circuit in which the components are not connected to each other, and the current is the same across each component

• A circuit in which the components are connected in branches, and the voltage is the same across each component but the current may vary.

• A circuit in which the components are connected in a loop, and the voltage varies across each component

How does the voltage behave in a parallel circuit?

• The voltage is zero in all branches

• The voltage increases in each branch

• The voltage remains constant across all branches.

• The voltage decreases in each branch

What is the equivalent resistance of resistors in a parallel circuit?

• 1/Req = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn

• Req = R1 - R2 - R3 - ... - Rn

• Req = R1 + R2 + R3 + ... + Rn

• Req = R1 * R2 * R3 * ... * Rn
