What is the main difference between electron flow and conventional flow in circuits?

• Both electron flow and conventional flow are from negative to positive.

• Electron flow is from positive to negative, while conventional flow is from negative to positive.

• Electron flow is from negative to positive, while conventional flow is from positive to negative.

• Both electron flow and conventional flow are from positive to negative.

In a series circuit, what happens if one bulb breaks?

• The other bulbs will shine brighter.

• The entire circuit stops working.

• The other bulbs will continue to shine.

• The circuit will short circuit.

Why is voltage the same across all components in a parallel circuit?

• Because the current is the same in all branches.

• Because the voltage is divided among the components.

• Because the components are connected in series.

• Because each component is connected directly to the battery terminals.

How does the total current in a parallel circuit relate to the current in each branch?

• The total current is the product of the currents in each branch.

• The total current is the average of the currents in each branch.

• The total current is the difference between the highest and lowest branch currents.

• The total current is the sum of the currents in each branch.

What happens to the total current if the resistance in one branch of a parallel circuit is doubled?

• The total current increases.

• The total current decreases.

• The total current becomes zero.

• The total current remains the same.

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

• Use the reciprocal of the sum of the reciprocals of each resistance.

• Add the resistances of all components.

• Subtract the smallest resistance from the largest.

• Multiply the resistances of all components.

Why is the total resistance in a parallel circuit less than the smallest individual resistance?

• Because the current is divided among multiple paths.

• Because the voltage is divided among multiple paths.

• Because the resistors are connected in series.

• Because the resistors are of different values.

Which formula can be used to calculate power consumption in a parallel circuit?

• Voltage squared divided by resistance.

• Current squared multiplied by resistance.

• Current divided by voltage.

• Voltage multiplied by resistance.

What is the power consumption of a 10 ohm resistor with a current of 0.6 amps?

• 3.6 watts

• 6 watts

• 36 watts

• 0.6 watts

How does increasing the voltage affect the current in a parallel circuit?

• The current becomes zero.

• The current decreases.

• The current increases.

• The current remains the same.
