Day#9

What is an electric circuit?

• A power source only

• A path for electric current to flow

• A group of batteries

• A type of wire

In a series circuit, how many paths does the current have?

• Two

• Four

• One

• Infinite

In which circuit does the current split into different branches?

• Series

• Parallel

• Closed

• Open

If one bulb goes out in a series circuit, what happens to the others?

• All go out

• Only that one goes out

• Others become brighter

• Nothing changes

Which type of circuit is used in home wiring?

• Series

• Parallel

• Mixed

• Short circuit

What happens to the brightness of bulbs in a series circuit as you add more bulbs?

• They get brighter

• They get dimmer

• No change

• They start blinking

What is the total resistance in a series circuit?

• The lowest resistance

• The highest resistance

• The sum of all resistances

• Zero

In a parallel circuit, the voltage across each branch is:

• Different

• The same

• Zero

• Half

Which circuit allows components to work independently?

• Series

• Parallel

• Both

• Neither

What happens to the total current in a parallel circuit?

• Decreases

• Becomes zero

• Splits across branches

• Doubles
