Electric Circuit
- Def: A electric circuit is a path in which electrons travel.
-
- - There are two types of circuits a Series circuit and a Parallel circuit
-
-
 
-
Voltaic Cell
Def: A source of energy which generates an electric current with chemical reactions involving two different metals separated by a conductor.
- Related Terms:
- - dry cell, wet cell, primary cell,secondary cell, fuel cell, solar cell
-
Battery
Def: Two or more cells connected together
-
Electrode
Def: A metal terminal in a cell or a battery (one of the two)
- Related Terms:- Electrolyte
-
Electrolyte
Def: A paste or solution that has the ability to conduct charges.
- Related Terms:- All cells
-
Dry Cell
Def: A cell in which an electrolyte made of paste can be found.
-
Wet Cell
Def: A cell in which a liquid electrolyte can be found.
-
Primary Cell
Def: A cell that can't be used more than once.
-
Secondary Cell
Def: A cell that has the ability to recharge and be used multiple times.
-
Fuel Cell
Def: A cell that can generate electricity through chemical reactions of fuel that is stored outside the cell.
-
Solar Cell
Def: A cell that can convert solar energy into electrical energy.
-
Terminal
Def: The points on a cell which must be connected with the circuit to make it work
- There is the negative terminal and the positive terminal
-
Switch
Def: A switch is a conductor that allows you to control whether to complete or break a circuit.
-
Open Circuit
Def: A open circuit is a circuit that has a gap or a break causing any device connected to it to stop working.
-
Electric Current
Def: The rate of movement of electric charge.
- Related Terms:- Electrical resistance
-
Coulomb (C)
Def: A coulomb is the unit of electric charge.
- One coulomb is the quantity of charge that is equal to the charge of 6.25×1018 electrons.
-
Ampere (A)
Def: An ampere is the unit of electric current.
- Electric current is measured using an ammeter
-
Electrical Resistance
Def: Electrical resistance stops electric current and converts the electrical energy to other forms of energy.
-
Resistor
Def: A resistor is a small device that can restrict the current through a component by a specific amount in a electric circuit.
- Types of resistors:
-
Load
Def: A load is a device that converts and transforms electrical energy into heat, motion, sound, or light.
E.g. A resistor, light bulb, microwave, fridge.
-
Potential Difference (voltage)
Def: The potential difference is the amount of work done per coulomb of charge which moves between the terminals of the cell.
- - A voltmeter is used to find the potential difference
- - potential difference= difference in potential energy (J)
- Charge (C)
-
Volt
Def: A volt is the unit used for potential difference and is equivalent to one joule per coulomb.
-
Circuit Diagram
Def: A diagram that uses simple symbols in order to represent the components and connections in an electuring circuit.
-
Series Circuit
Def: A circuit where there is only one path that electons can flow.
-
Parallel Circuit
Def: A circuit where there are more than one path in which electrons can flow.
-
Ohm's Law
Def: The ratio of potential difference to current is resistance.
-
Ohm
Def: An ohm is the unit for resistance.
-
Superconductor
Def: A mamaterial in which electric charge can eas I'll flow with no resistance.
-
Non-Ohmic
Def: Something that does not follow ohm's law.
-
Loads in Series
Def: Loats that come one after another in a series circuit.
- The current still stays the same throughout all points in a series circuit because the electrons are still only traveling down one path ( IT = I1 = I2 = I3 )
- Although the potential difference ends up splitting up because the energy has to be shared by all loads ( VT = V1 + V2 + V3)
- More loads in series also means a greater resistance, the total resistance is equal to the sum of the resistance
-
Loads in Parallel
Def: Loads that are positioned throughout the parallel circuit on different paths.
