Understanding Current and Circuits

What is the direction of conventional current flow?

• From negative to positive terminal.

• From positive to negative terminal.

• From ground to positive terminal.

• From negative terminal to ground.

How do electrons flow in a circuit?

• Electrons flow from the negative terminal to the positive terminal in a circuit.

• Electrons flow from the positive terminal to the negative terminal.

• Electrons do not flow in a circuit.

• Electrons flow in a circular motion around the circuit.

What is a key characteristic of a series circuit?

• The components are connected in parallel.

• The total resistance decreases with more components.

• The voltage is the same across all components.

• The current is the same through all components.

In a parallel circuit, how does the voltage across each branch compare?

• The voltage is lower in one branch than the others.

• The voltage across each branch is the same.

• The voltage is higher in one branch than the others.

• The voltage varies in each branch.

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

• The total resistance remains the same.

• The total resistance increases.

• The total resistance decreases.

• The total resistance fluctuates randomly.

How does current behave in a parallel circuit with multiple paths?

• Current is zero in a parallel circuit.

• Current remains constant across all paths.

• Current divides among multiple paths in a parallel circuit.

• Current flows only through one path at a time.

What is the role of a battery in a circuit?

• To convert electrical energy into mechanical energy.

• The role of a battery in a circuit is to supply electrical energy.

• To store electrical energy for later use.

• To regulate the temperature of the circuit.

How can you represent a circuit diagrammatically?

• Use standardized symbols and connect them with lines to represent electrical connections.

• Use only colors to represent different components.

• Draw freehand without any symbols or lines.

• Label components with numbers instead of symbols.

What is the effect of adding a resistor in series on the total current?

• The total current increases.

• The total current fluctuates.

• The total current remains the same.

• The total current decreases.

In a parallel circuit, what happens to the total current as more branches are added?

• The total current fluctuates randomly with added branches.

• The total current remains the same regardless of branches added.

• The total current increases as more branches are added.

• The total current decreases as more branches are added.
