3 resistors are connected to a 9 V battery n a series circuit, the first resistor uses 6 V, the second uses 2 V. How much voltage does the third resistor use?

• 1 V
• 2 V
• 3 V
• 9 V

As the number of resistors increase, the total resistance ___________ and the total current ____________

• Increase, decrease
• Decrease, increase
• Increase, increase
• Decrease, decrease

If you increase the total voltage in a circuit how will it affect the light bulb?

• It will burn out
• The bulb will get brighter
• It will get dimmer

What is a series circuit?

• The transfer of electrons from one object to another
• A circuit with a single path the current follows
• A circuit that goes in multiple directions
• A circuit that takes place in a series of events

What happens when you add a second bulb to a series circuit?

• The first bulb gets brighter
• The second bulb will be as bright as the first because they both get full power
• The circuit will no longer work
• Both bulbs will be half as bright because the voltage is divided by two now
