Brainpop Electric Circuits

A circuit is...

• A way of routing electricity along a path

• When you measure how much an item weighs

What is the function of a power source in circuit?

• To cause motion of protons.

• To generate a steady supply of electrons.

• To deflect any static electricity.

How does a SWITCH work?

• The switch increases the amount of electrons flowing in the wires.

• The switch makes the electrons in a wire move faster.

• The switch opens or closes the circuit.

When electrons move from one place to another you get...

• a solid to a liquid

• electricity

• evaporation

How will each change affect the current in the circuit?

• current will be half

• Lower the potential difference from 9V to 3V

• current will be 1/3rd as strong

• Change the resistance from 100 Ω to 400 Ω

• current will double

• Double the resistance of the bulbs

• current will be 1/4th as strong

• Double the number of batteries

Since there are multiple pathways the current can take from the positive side of the battery to the negative side, in a ​ (a)   circuit, the ​ (b)   is divided up among the pathways, but the potential, or voltage, is the same for each pathway. ​In ​ (c)   circuits with only one pathway for the current, the ​ (d)   , or voltage, is divided up among the different elements.

• parallel

• current

• series

• potential

In order for electricity to be useful, we need...

• A steady flow electricity.

• An overflow of protons.

• A light bulb that never runs out.
