This video explains a parallel circuit and how to find the amps, resistance, and voltage given certain information. Review of parallel circuits with review problems.
An electrical current moves through this wire. The plastic surrounding this wire is an insulator. An insulator is a weak conductor of electricity. Insulators are used to protect people from electrical current.
In a series circuit the electricity would stop flowing if one of the light bulbs were broken. A parallel circuit has two or more paths for electricity to flow that are parallel to each other. The multiple paths allow electricity to continue to flow even if one path is broken by a broken light bulb.
This light bulb continues to glow because the path is not broken and electricity still has one path to flow through. The other path is broken because of the broken light bulb. In the picture above notice how electrons have two paths to flow through.
This is a parallel circuit. A parallel circuit is a closed circuit with two or more paths for electricity to flow through.
The wire inside the plastic in this circuit is a conductor. A conductor is a material that conducts electricity well. An example of a conductor is copper wire. Conductors are used to transport electricity.
Electrical resistance is the difficulty of electricity moving through a wire. It can be explained as how difficult it is for electricity to flow through. Resistance is measure in Ohms. Resistance is like a force stopping electricity.
The opposite to resistance is voltage. Voltage is the difference of electrical potential between two points. As the voltage increases the amount of electricity moving through the wire increases. Voltage is measured in volts. Voltage is like a force pushing electricity.
A switch is a device that can complete or break a circuit. A switch allows you to control the flow of electricity. If the switch doesn't connect the two wires it separates it breaks the circuit. A switch inserted in this circuit would allow you to turn on/off the light.
This wire contains electrical current. Electrical current is the flow of electrical charge. Current is measured in Amps. Electrical current is a result of voltage and resistance. It can be described as the amount of electricity used.
This video explains electrical current. A simple explanation on how an electrical circuit operates.
