With simple parallel circuits, all components are connected between the same two sets of electrically common points, creating multiple paths for the current ...

Differentiating among the various kinds of electric circuits is easy and fun for students with this hands-on sorting activity! Great way for kids to review ...

Here, we have three resistors (labeled R1, R2, and R3) connected in a long chain from one terminal of the battery to the other.

In this circuit, we have two loops for the current to flow through: one from 1 to 2 to 5 to 6 and back to 1 again, and another from 1 to ...

Again, we have three resistors, but this time they form more than one continuous path for current to flow. There's one path from 1 to 2 to 7 to 8 and back ...

In a purely parallel circuit, there are never more than two sets of electrically common points, no matter how many components are connected.

With simple parallel circuits, all components are connected between the same two sets of electrically common points, creating multiple paths for the current ...

Simple Circuit: A simple electric circuit in which a closed path for current to flow is supplied by conductors (usually metal wires) connecting a load to ...

Instead, they look like small tubes or cylinders with two wires protruding for connection to a circuit. Here is a sampling of different kinds ...

Differentiating instruction, integrating science into reading, AND addressing standards like Common Core is daunting. But this passage set knocks out all ...

The above circuit applies Ohm's law with the fundamental formula: voltage is equal to resistance multiplied by current. The resistance is in Ohms and is ...

This circuit allows for the creation of a very high impedance input and low impedance output. This is useful to interface logic levels between two ...

A semiconductor material is one whose electrical properties lie in between those of insulators and good conductors.Example are:Germanium and silicon.

All we've been given here to start with is the battery voltage (10 volts) and the circuit current (2 amps). We don't know the resistor's resistance in ohms ...

Reducing a combination circuit: This combination of seven resistors has both series and parallel parts. Each is identified and reduced to an equivalent ...

The choice of each current's direction is entirely arbitrary, just as in the Branch Current method, but the resulting equations are easier to solve if the ...

Many more circuits are available with operational amplifiers, but understanding these fundamental 10 circuits allows you to easily study more complex ...

Most symbols used on a wiring diagram look like abstract versions of the real objects they represent. For example, a switch will be a break in the line with ...

This circuit is neither simple series nor simple parallel. Rather, it contains elements of both. The current exits the bottom of the battery splits up to ...

An amplifier is useful not just because it lets you add, subtract, or compare voltages. Many circuits allow you to modify signals. Let's see the most basic ...

Various cells and batteries (top-left to bottom-right): two AA, one D, one handheld ham radio battery, two 9-volt (PP3), two AAA, one C, one camcorder ...

The basic idea of a “series” connection is that components are connected end-to-end in a line to form a single path through which current can flow:

By adding resistors in parallel on the inverting input pin of the inverting operation amplifier circuit, all the voltages are summed.
