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

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.

If the total current in a parallel circuit is 2601A and all three resistors are identical, what is the current through R3 if you have a voltage of 12?

• 867.0
• 205.0
• 354.0
• 976.0

How to find power

• V=IR
• R+V/I
• P=VI
• P= RT
