Series and Parallel Circuits

Front

What is a conductor?

Back

A material in which electrons can move easily, allowing electric current to flow.

Front

What is a parallel circuit?

Back

A circuit that has more than one loop; if one component fails, the others continue to operate.

Front

What is current measured in?

Back

Amps (Amperes), which measure the flow of electric charge.

Front

True or False: In a parallel circuit, if one connection is broken, all of the connections stop working.

Back

False.

Front

What happens to light bulbs in a parallel circuit when more are added?

Back

They all remain bright.

Front

What is an insulator?

Back

A material that does not allow electrons to move freely, preventing electric current from flowing.

Front

What is a series circuit?

Back

A circuit with only one loop; if one component fails, the entire circuit stops working.

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in Ohms.

Front

What is the formula for calculating total resistance in a series circuit?

Back

R_total = R1 + R2 + R3 + ... (sum of all resistances).

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ... (inverse of the sum of the inverses of all resistances).
