Electrical Circuits Test Review

What would you need to do to the voltage if you wanted to increase the current in a series circuit?

• Increase

• Greater

• Decrease

• Smaller

What is the current of a series circuit with a total resistance of 10 ohms and a voltage of 110 V

• 0.09 A

• 11.0 A

• 1100.0 A

• 10.0 A

What is the difference in finding total resistance in a series circuit vs. in a Parallel circuit?

• No Difference

• For series use inverse equation, for parallel add resistances up.

• For series add up resistances, for parallel add up resistances

• For series add up resistances, for parallel use inverse equation

A parallel circuit has 6 ohm, 10 ohm, 12 ohm and 15 ohm resistors and a total voltage of 10V, what is the current?

answer given in nearest whole number

• 1.0 A

• 2.0 A

• 3.0 A

• 4.0 A

If a series circuit of three bulbs is rearranged into a parallel circuit, what will happen to the brightness of three bulbs

• The bulbs will turn off due to an incomplete supply of electricity.

• All three bulbs will have the same amount of luminosity once rearranged into a parallel circuit but will be dimmer than in parallel.

• All three bulbs will have the same amount of luminosity once rearranged into a parallel circuit but will be brighter than in parallel.

• The bulb next to the battery will be brightest and each bulb will be dimmer than the one before.
