In which type of circuit is there only one path for current to flow?
In a series circuit, there is only one path for current to flow.
What happens to the current in a series circuit?
In a series circuit, the current remains the same through all components.
Which of the following statements is true about a parallel circuit?
In a parallel circuit, current has multiple paths to flow.
What happens if one branch of a parallel circuit breaks?
If one branch of a parallel circuit breaks, only the broken branch stops conducting current.
Who invented the electric bulb?
