What Makes A Circuit Work

What you built with the battery wire and bulb in step 3 is called an open circuit.

What makes a circuit work. It provides the force or pressure for blood to circulate. Materials that allow electric current to pass through them easily called conductors can be used to link the positive and negative ends of a battery creating a circuit. The blood circulating through the body supplies various organs like your muscles brain and digestive system a battery or generator produces voltage the force that drives current through the circuit. The image below illustrates various voltages.

Electric current takes the path of least resistance so in a short circuit the current will bypass other parallel paths and travel through the direct connection. In a parallel circuit electricity can pass along different paths to power different loads. Your heart is the pump that drives the blood circulation in the body. To turn out the light the circuit needs to be broken by adding a switch.

A short circuit is a direct connection between two points in a circuit that aren t supposed to be directly connected such as the two terminals of a power supply. Just as your heart produces the pressure to make blood circulate a battery or generator produces the pressure or force to push electrons around a circuit. A circuit is a complete path around which electricity can flow. Voltage is the force and is measured in volts v.

Electricity is pushed around a circuit by a source of power. A series circuit has only one path of electricity. We re finally ready to make electricity work for us. It does not matter where the switch goes as the effect is the same.

Short circuits are another matter entirely. Moving quickly through exercises makes this a good cardiovascular workout. Voltage is the driving force that makes every thing work. It must include a source of electricity such as a battery.

This source can be a battery. Electricity or current will flow. Current is the flow of electricity around a circuit. Electricity from a battery has to flow out one end the negative or end and back in through the positive end in order to work.

Using proper technique as you work through your circuit will improve your flexibility. A typical flashlight battery produces 1 5v and the standard household electrical voltage is 110v or 220v. Take the simple case of an electric light. It provides power for more than one electrical load.

When talking about electrical circuits there are three main quantities to consider voltage current and resistance. To most people this is probably the most people familiar quantity. In order for electricity to start flowing you need a closed circuit.
