week 32 review electricity

A circuit that has more than one path for electricity to follow is a...

• series
• static
• broken
• parallel

When the switch is closed, the light

• comes on
• stays off
• burns out

If the lights are on, the circuit is

• closed
• open

If the lights are off, the circuit is

• closed
• open

What is the current through the 4Ω resistor?

• Not enough information.

• 3.5 A

• 9 A

• 14 A

What is the total resistance of the circuit?

• 9 Ω

• 14 Ω

• 1.08 Ω

• .923 Ω

The circuit diagram represents four light bulbs connected to a battery. All four bulbs are lit. Which bulb can burn out while allowing the other three bulbs to remain lit?

• Either B1 or B2

• Either B1 or B3

• Either B2 or B4

• Either B3 or B4

In a series circuit which of the following is the same  throughout the circuit

• Resistance
• Voltage
• Current
• None of the above

A circuit with 3 resistors, 10 Ohms, 30 Ohms and 20 Ohms are in series. What is the total resistance

• 30 Ohms
• 50 Ohms
• 60 Ohms
