series
parallel
What type of circuit has only one path to follow and there can be more than one load on this path?
series
parallel
Which is TRUE about series circuit?
It only contains more than one load and has more than one path on which electrons can flow.
The loads don't have to share the voltage, so it doesn't matter how many bulbs you add.
It has more than one available path for the electrons to flow through, one bulb burning out won't prevent the other loads from receiving current.
The circuit follows one path, and all the light bulbs share the voltage.
Which is NOT TRUE about parallel circuit?
It only contains more than one load and has more than one path on which electrons can flow.
The loads don't have to share the voltage, so it doesn't matter how many bulbs you add.
It has more than one available path for the electrons to flow through, one bulb burning out won't prevent the other loads from receiving current.
The circuit follows one path, and all the light bulbs share the voltage.
What does it mean if the resistor has a HIGH resistance?

There is no current at all.
Which of the following is TRUE about resistance?
If the resistor has a low resistance, current can flow a lot.
If the resistor has a low resistance, current flow is fewer.
If the resistor has a high resistance, current can flow a lot.
If the resistor has a high resistance, no current can flow.
If the voltage across a resistance is DOUBLED, what will happen to the current?
The current will decrease.
