Series and Parallel Circuits

What is a Series Circuit?

• An electric circuit with a single path for current to flow.

• An electric circuit with multiple paths for current to flow.

• A circuit that only works with batteries.

• A circuit that can only be used in series with other circuits.

What is the effect of adding more resistors in series?

• The total resistance decreases.

• The total resistance remains the same.

• The total resistance increases.

• The total resistance fluctuates.

What is the unit of electrical resistance?

• Volt (V)

• Ampere (A)

• Ohm (Ω)

• Watt (W)

What is the purpose of a fuse in a circuit?

• To increase the current flow in the circuit.

• To protect the circuit from overload by breaking the circuit if the current is too high.

• To store electrical energy for later use.

• To convert AC to DC voltage.

What is the effect of adding more resistors in parallel?

• The total resistance increases.

• The total resistance remains the same.

• The total resistance decreases.

• The total resistance becomes infinite.

What is an open circuit?

• A pathway that does not allow an electric current to flow.

• A closed loop that allows electric current to flow.

• A circuit that has a short circuit condition.

• A circuit that is connected to a power source but has no load.

What happens to the current in a parallel circuit if one component fails?

• The current stops flowing entirely.

• The current can still flow through other pathways.

• The voltage increases across the remaining components.

• The circuit becomes a series circuit.

What is a closed circuit?

• A pathway that allows an electric current to flow freely - light is on!

• A pathway that prevents electric current from flowing - light is off.

• A circuit that has multiple paths for current to flow.

• A circuit that only works with batteries.

What happens to the current in a series circuit if one component fails?

• The current continues to flow normally.

• The current stops flowing in the entire circuit.

• The current increases in the remaining components.

• The current flows only through the failed component.

What is Ohm's Law?

• Voltage = Current x Resistance.

• Power = Voltage x Current.

• Resistance = Voltage / Current.

• Current = Voltage + Resistance.
