What is the purpose of a circuit?

• To cook food

• To play music

• To provide a path for electrical current to flow

• To write a novel

How can you identify a resistor in a circuit?

• By analyzing the color bands on the resistor and decoding them using a color code chart.

• By tasting it to determine its resistance

• By listening to the sound it makes when electricity passes through it

• By smelling it to detect a specific odor

In a series circuit, what happens to the current?

• Stops

• Remains constant

• Decreases

• Fluctuates

What is the voltage across each component in a series circuit?

• The voltage across each component in a series circuit is inversely proportional to the resistance of the component.

• The voltage across each component in a series circuit is different for each component.

• The voltage across each component in a series circuit is dependent on the current flowing through the circuit.

• The voltage across each component in a series circuit is the same.

How do you calculate the total resistance in a series circuit?

• Total resistance = R1 - R2 - R3 - ... - Rn

• Total resistance = R1 * R2 * R3 * ... * Rn

• Total resistance = R1 + R2 + R3 + ... + Rn

• Total resistance = R1 / R2 / R3 / ... / Rn

What happens to the total current in a parallel circuit?

• The total current decreases

• The total current becomes zero

• The total current remains the same.

• The total current increases

How do you identify a capacitor in a circuit?

• Identify a component with two terminals and a cylindrical shape, possibly labeled with capacitance value.

• Search for a component with four terminals and a circular shape

• Identify a component with a single terminal and a triangular shape

• Look for a component with three terminals and a square shape

What is the main difference between series and parallel circuits?

• The color of the wires used

• The main difference between series and parallel circuits is how components are connected and how current flows through them.

• The shape of the components

• The voltage supplied

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

• Voltage and current are directly proportional

• Voltage and current are inversely proportional

• Voltage has no effect on current

• Current has no effect on voltage

How does a diode behave in a circuit?

• A diode allows current to flow in both directions

• A diode blocks current flow in both directions

• A diode allows current flow in one direction only

• A diode has no effect on current flow
