What are the main components of a circuit?
Resistors, insolates and more items

What is AC/DC Current?
Both AC and DC describe types of current flow in a circuit. In Direct current(DC) the electric charge (current) only flows in one direction. Electric charge in alternating current (AC) on the other hand, changes direction periodically

What is the use of a parallel circuit
it has 2 or more paths so you can connect more things such as light bulbs

What is the difference between oxidation and combustion?
In combustion organic com pounds are completely burnt and get oxidized to CO2 and water. The process needs oxygen to occur. ... On the other hand in oxidation, oxygen is gained and hydrogen molecules or the electrons are lost thereby giving the element or the compound an oxidized form.

water pollution is caused by several reasons here are some of the major ones sewage, plastic, garbage.
What causes water pollution?
200
Lightbulb, wire, Battery
What is 3 things you need to make a circuit?
200
Is AC or DC more dangerous?
AC is considered to be more dangerous
200
how many paths does a series circuit have
A series only has one path
200
What is a combustion reaction in chemistry?
Combustion reactions always involve molecular oxygen O2. Anytime anything burns (in the usual sense), it is a combustion reaction. Combustion reactions are almost always exothermic (i.e., they give off heat). ... When organic molecules combust the reaction products are carbon dioxide and water (as well as heat).

water pollution is detected in laboratories where small samples of water are tested
how do we detect water pollution?
300
What is one item used to complete an incomplete circuit?
A Switch
300
Are home appliances Ac or Dc?
Most home appliances are Ac
300
how many paths can you have for a parallel circuit
you can up to 6 paths
300
Is burning an oxidation reaction?
Fire is burning, which is combustion, and combustion is a type of oxidation reaction. Oxidation means combined chemically with oxygen . Oxidation is an exothermic reaction, meaning it gives releases heat energy

Water contains many compounds that are made of carbon and carbonate. Carbonite works as a buffer in water and this is very important component. when calcium reacts with carbonite solid substance is formed, that is called lime
What causes white deposits on shower and bathroom walls?
400
What kind of wire should you use for a circuit?
A copper wire
400
is AC or DC in our homes?
Both AC and DC our in our homes
400
How do you make a parallel circuit?
Choose this method as a slightly advanced project Gather the main components of a parallel circuit Prepare your wires. ... Connect the first lightbulb to the battery Begin to connect the switch to the battery Connect the switch to the first lightbulb

What is needed for a combustion reaction?
The Fire Triangle. Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Heat (ignition temperature) to start and continue the combustion process.

poring preparation rain water dissolves gases such as carbon dioxide and acids work together to form acid rain
What is acid rain how does it develop?
500
could a penny complete a circuit?
Yes is Can
500
The reason people have ac products is because less power small items have ac and big products have dc
why do most people have AC currents instead of DC currents in there home?
500
What is parallel in electrical wiring?
Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur frequently. Components connected in parallel are connected along multiple paths, so the same voltage is applied to each component.
500
What is the difference between burning and combustion?
The basic difference is that combustion is heating and no flames are produced whereas in burning most of the energy is converted to light energy and this results in less heat energy as compared to combustion. ... when in a combustion process a flame is produced it is referred to burning.
