Activity 4: Simple Circuit, Conductors, and Insulators

can flow via a closed loop made up of a power source, conductive route, and load in a simple curcuit

Electric current

Effective energy transmission is made possible by ____, like metals, which permit electric charge to flow easily.

Conductors

Blocks the flow and act as barriers for protection in a wide range of electrical applications

Insulators

How many different ways can you combine the three components in procedure 4.6.1

6 different ways

In activity 4, is there a difference in the intensity of the current if you change the order in which the components are connected?

No

What happened when the type A bulb was replaced with a type B bulb?

brightness of light bulb changes

What happened when the jumper plugs were replaced with connecting leads?

No changes

Does more or less current flow through the 100-ohm resistor, compared to the 47-ohm resistor

Less current flows through the 100-ohm resistor than through the 47-ohm resistor.

Larger resistance opposes current flow more, resulting in:

less current

Smaller resistance:

more current
