Understanding DC Parallel Circuits

What happens to the voltage across each component in a parallel circuit?

• The voltage varies depending on the component.

• The voltage is the same across all components.

• The voltage doubles with each additional component.

• There is no voltage in a parallel circuit.

If you have a parallel circuit with a 9V battery, what is the voltage across each resistor connected in parallel?

• 18V

• 9V

• 4.5V

• 0V

In a parallel circuit, if one of the components fails, what happens to the voltage across the remaining components?

• It increases.

• It decreases.

• It remains the same.

• It drops to zero.

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

• Because each component has its own direct path to the voltage source.

• Because the components share the same voltage source.

• Because the resistance of each component adds up.

• Because the current is the same through all components.

If a parallel circuit is powered by a 12V battery, what is the voltage across a resistor connected in parallel?

• 24V

• 12V

• 6V

• 0V

What would be the effect on the voltage across each component if the voltage of the battery in a parallel circuit is increased?

• The voltage across each component decreases.

• The voltage across each component increases proportionally.

• The voltage across each component remains unchanged.

• The voltage across each component doubles.

In a parallel circuit with multiple resistors, if the voltage source is 5V, what is the voltage across a 100Ω resistor?

• 10V

• 5V

• 2.5V

• 0V

How does the voltage in a parallel circuit compare to the voltage of the battery supplying the circuit?

• It is half the voltage of the battery.

• It is twice the voltage of the battery.

• It is the same as the voltage of the battery.

• It has no relation to the voltage of the battery.

If a parallel circuit consists of three resistors and is connected to a 6V battery, what is the voltage across the third resistor?

• 18V

• 6V

• 3V

• 2V

Why does the voltage not decrease as it passes through each component in a parallel circuit?

• Because the components generate voltage.

• Because the voltage is divided equally among the components.

• Because each component is connected directly to the voltage source.

• Because the current decreases instead.
