Current Electricity

In a series circuit which of the following is the same  throughout the circuit

• Resistance
• Voltage
• Current
• None of the above

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 in a series circuit, the total resistance ___________ and the total current ____________

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

If you increase the resistance of a parallel circuit by adding more loads, what happens?

• Current decreases at the source
• Current increases at the souce
• Electrons disappear
• Bulbs get brighter

If you increase the voltage of the source in a  parallel circuit, what happens?

• Current decreases
• Current increases
• Electrons disappear
• Bulbs get dimmer

If you decrease the voltage of a series circuit, what happens?

• Current decreases
• Current increases
• Electrons disappear
• Bulbs get brighter

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.
