Understanding Electric Circuits

What is the formula for Ohm's Law?

In a series circuit, if one component fails, what happens to the entire circuit?

• The circuit continues to work.

• The circuit stops working.

• Only the failed component stops working.

• The voltage increases.

Which of the following is a characteristic of a parallel circuit?

• The current is the same through all components.

• The voltage is the same across all components.

• The resistance is the same across all components.

• The power is the same across all components.
