light bulbs and appliances are examples of this part of a circuit
What is a load
100
Potential difference is...
What is voltage
100
if a circuit has 12 V and a current of 6 A what is the resistance
What is 2 Ohms
200
Can potential energy become kinetic energy?
YES!
200
What part of the atom moves to create electricity?
What is an electron?
200
can turn a circuit on or off
What is a switch
200
the rate of flow of charge through a circuit
What is current
200
if a circuit has 4 A of current and a resistance of 4 Ohms, what is the voltage?
What is 16V
300
What type of energy is found in an electrochemical cell?
What is electric potential energy?
300
How does current change when voltage increases?
What is increases?
300
What happens if you connect a circuit that does not have a load?
It burns/catches fire/blows up
300
the opposition to flow of current in a circuit
What is resistance
300
If a circuit has 10 V and a load with a resistance of 5 Ohms what is the current?
What is 2 A
400
How can you create current from an electrochemical cell?
What is create a circuit?
400
Why doesn't electricity come out of this battery?
Because it isn't connected to a circuit
400
What is this?
What is a resistor?
400
How can you increase the current in this circuit?
Remove a lightbulb/increase voltage
400
If a light bulb with 3 ohms of resistance is removed from a circuit connected to a 9V battery producing 3A of current, what will happen to the voltage?
NOTHING
500
What is an electrochemical cell made of?
What is an electrolyte and electrodes?
500
Why don't we use static electricity to power our homes?
It doesn't move, so it doesn't do any work!
500
What does a resistor do?
What is slows current?
500
as resistance in a circuit decreases the current does what
What is increases
500
How many amps would statically charged balloon have?
NONE! Static charge does not move, so there is no current
