Parallel Circiuts Test

What voltage is necessary to produce a current of 200 amperes through a resistance of 100 Ω?

• 100 volts
• 20000 volts
• 1000 volts
• 500 volts

What resistance would produce a current of 120 amps from a 6-V battery?

• 0.5 ohms
• 1 ohm
• 10 ohms
• 0.05 ohms

How many paths for current to flow in a series circuit?

• 2
• 3
• 4
• 1

What happens to the other bulbs if one of the bulbs in a series circuit is busted?

• The other bulbs will also go out.
• The other bulbs will get brighter.
• The other bulbs will stay the same.
• The other bulbs will flicker.

The unit for resistance is:

• ohms

• volts

• moles

• amperes

The unit for current is:

• ohms

• volts

• amperes

• moles

Why are resistors important in some circuits?

• Becuase they slow down the flow of electrons so the circuit doesn't over heat
• Because they protect against loss of charg
• Because they complete the circuit
• Because they control the flow of energy up and down

What is the voltage drop for each resistor?

• 9 V: all resistors have the same voltage in a parallel circuit
• 9V: there is only one resistor in this circuit
• Trick question! They all have different voltages!
• Trick question! They all have the same current!

what is this symbol for?

• light bulb
• switch
• battery
• resistor

Resistance?

• 1/Rp = (1/5) + (1/8) + (1/3)

• 120 Ω

• 1.5189873 Ω

• 1/Rp = (1/5) * (1/8) * (1/3)
