It produces heat/light
The things you need for your curcuit are: A light bulb, Bell wire, A Battery and a conducter ex. pin, paper clip Attach the bulb together with the battery using the bell wire. With the two ends of the wire connect to the conducter and see if light bulb comes on.
When you have a light bulb in front of each other (all connected to wires to a battery)
If there are no gaps in a curcuit, it is a closed curcuit.
V = I * R. 1.5 = 8*IThe current flow is 3/16 Amps.
A flashlight is an example of a series circuit; a battery in series with a switch in series with a bulb.
Car curcuit
a test lamp i literrally a bulb connected to two wires. it was used to check if you had any current or voltage in a circuit. you would just take the build with the two wires and touch it with the curcuit. if the bulb lights up means that you have a complete circuit if not it means that the curcuit is working. The test lamp is like a medival tool to a multimeter
A Parrallel Curcuit has more then 1 pathway
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Thomas Edison invented the Parallel circuit while working on the electric light bulb around 1879.
series-parallel curcuit
Yes! Charlie macdonell rocks! Likechameleon curcuit? have you seen charlieissocoollike? No why not
