100
What is a series circuit?
A circuit that has only one path for current to flow
200
What are the characteristics of conductors?
They allow the flow of charges easily
200
What does I represent in Ohm's Law?
Current (measured in Amps)
200
Draw the symbol for a two cell battery.
Four lines two short and two long
Or
1 short and 1 long
200
Name one non-renewable source of energy.
Nuclear, fossil fuels, natural gas, oil, etc.
200
What is a parallel circuit?
A circuit that has more than one path for current to flow.
300
What do plastic, glass, wood, dry air all have in common?
They are all insulators
300
What current flows in a circuit that has a 6 V battery and 2 Ohm light bulb?
3 A
300
Draw a circuit with 1 cell in series and 1 lightbulb.
Drawing shown
300
What is something that melts or breaks apart when there is too much current running through it?
Fuse
300
Voltage in series is...
Shared
400
What is electrical resistance?
It is a resistance to the flow of charges
400
What voltage is required for a circuit that needs 3 A to flow across a resistor of 4 Ohms?
12 V
400
Draw 1 cell in series, 2 bulbs in parallel and an ammeter measuring the first bulb.
Drawing shown
400
What are two factors that affect resistance in circuits?
Thickness of wire, material, length of wire, heat
400
Current in Series is
Constant
500
Which direction do electrons flow in a circuit.
From the negative terminal of the battery to the positive terminal.
500
A circuit has a voltage of 12V and a current of 3A. What is the resistance (including units). SHOW YOUR WORK.
4 ohms
500
Draw two cells in parallel, 1 light in series, 2 motors in parallel and a switch controlling one motor and light. Draw a voltmeter measuring the voltage across the light.
Drawing shown.
500
What types of circuits are found in buildings or homes and why?
Parallel because if one part stops working or overloads it won't affect the whole building.
500
Which type of circuit will allow lightbulbs to shine brighter if there are multiple and why?
Parallel because the voltage is constant between lightbulbs.
