Can you help me with questions 1 and 2 please? Thank you. Batteries and Bulbs Concepts: Schematic Complete circuits Current A. Series and Parallel Circuits Two light bulbs can be hooked to a battery in two different ways. series or parallel The light bulbs in series (#1,#2) are drawn schematically as N1 Battery The light bulbs in parallel (#3,#4) are drawn schematically as Battery Pre-lab Questions: 1. If a light bulb is hooked up to batteries, do you think the brightness of the bulb will depend on how many batteries you use? why or why not 2. If two identical bulbs are hooked up in series and two more identical are hooked up in parallel as shown, rank the four bulbs (by using the locations in the circuits above) from brightest to the least bright. Explain the reasons for your rankings of all four bulbs. uote: Never use more than two batteries. The light bulbs can't take it. Procedures: 1 Discuss vour pre lab prediction #1

Explanation / Answer

1

The brightness (power) of idential bulbs depends on current flow throw them. As using more number of batteries used in series.

2

The current flow in the series bulbs is same and maximum curretn in the circuit. the curretn divides in the parallel. So, the brightness of the bulbs in series are more than that of bulbs in parallel.

Rank: B1=B2<B3=B4
