# Electricity in Simple, Series, and Parallel Circuits

Module by: Rudy Lopes. E-mail the author

Summary: Concepts of Ohm's Law, power, current, and voltage as they apply to simple circuits, series circuits, and parallel circuits are covered in these tutorials.

Ohm's Law -- Ohm's Law describes the fundamental relationship between voltage, resistance, and current. This Formula Solver! Series program shows the step-by-step solution for using any two values (which you can enter yourself) to find the third.

Current in a Simple Circuit -- Current is defined as the flow of electricity through a circuit over time. This Formula Solver! Series program shows the step-by-step solution for finding current, charge, or time from the other two values (which you can enter yourself).

Current in a Parallel Circuit -- Current is a function of voltage and resistance. This Formula Solver! Series program shows the step-by-step solution for finding current in parallel circuits using your own voltage and resistance values.

Power in a Simple Circuit -- In the world of electricity, power is the product of current and voltage. This Formula Solver! Series program shows the step-by-step solution for finding power, current, or voltage from the other two values (which you can enter yourself).

Power in a Parallel Circuit -- In parallel circuits, power is a function of current and voltage. This Formula Solver! Series program shows the step-by-step solution for using voltage and resistance to find current and power (all with your own values).

Resistance in a Series Circuit -- This Formula Solver! Series program shows the step-by-step solution for finding resistance in a series circuit (using up to four resistance values which you can enter yourself).

Resistance in a Parallel Circuit -- This Formula Solver! Series program shows the step-by-step solution for finding electrical resistance in parallel circuits (using up to four resistance values which you can enter yourself).

### Add module to:

My Favorites (?)

'My Favorites' is a special kind of lens which you can use to bookmark modules and collections. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need an account to use 'My Favorites'.

#### Definition of a lens

##### Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
