## RL Circuits Class 8 MCQ With Answers

• A wire
• A switch
• A battery
• A light bulb

### 2. What is wrong with the circuit?

• The light is not big enough
• it needs more wires
• The wires are not closed
• Another energy source is needed

• true
• false

### 4. A complete electric circuit that allows electrons to flow along an uninterrupted path is called a/n ___________________.

• Open circuit
• Closed ciruit
• Electric circuit
• Series circuit

• Battery
• Light bulb
• Wire
• All of them

### 6. Will the light bulb in this circuit light and why/why not?

• yes, because it has two batteries
• no, because the switch is open
• yes, because it is in a circuit
• no, because the bulb is burned out

### 7. Open circuit or closed circuit?Will the light bulb light up?

• Light bulb WILL light up
• Closed circuit
• Light bulb WILL NOT light up
• Both A & B

### 8. A/n ______________________________________ is one in which there is an opening that does not allow current to flow.

• Open circuit
• Closed circuit
• Series circuit
• Parallel ciruit

### 9. Look at the picture.  Why won't the light bulb light up?

• The wires from the light bulb are not connected to the battery
• The switch is not closed to form a complete circuit
• The wires from the light bulb are not connected to the switch
• The wires from the battery are not connected to the switch

### 10. What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of electrical current
• the pathway that electrical current flows
• to add more power to the circuit

• ON
• OFF

### 12. Current is...

• how fast the electrons are moving
• the flow of electrical charge
• the power source
• the amount of energy gained/lost across two points

### 13. What is a circuit that only has ONE path for electricity to flow?

• series circuit
• closed circuit
• parallel circuit
• light bulb

• open
• closed

### 15. Which best describes a simple series circuit?

• Electricity flows along one pathway.
• The flow of electricity comes from the switch.
• Electricity flows along many pathways.
• The flow of electricity comes from the light bulb.

• closed
• open

### 17. When wires are connected to a battery and a lightbulb in a circuit, the lightbulb is light. Which types of energy are produced by the battery and lightbulb?

• Electrical and light
• electrical and sound
• sound and light
• all of the above
