Electricity

• The current is the same at all points in a series circuit.
• voltmeter measures voltage in a circuit
• A series circuit's current never ends unless its broken
• In a parallel circuit, if one component breaks then it will not affect other components
• Two cells = one battery
• The more bulbs there are in a circuit, the dimmer the light is
• High voltage moves a bigger current
• If one wire breaks in a parallel circuit, the current will still flow through other wires
• If one bulb breaks in a circuit, the other will also turn off because the current continues through the filament
• The difference between a series and a parallel circuit is the series circuit has the same wire all through out, but the parallel circuit has branches of different wires
• a voltmeter measures the amount of voltage in a circuit
• voltage is described as the pressure that pushes electricity through the circuit
• a resistor slows down the current flowing through the circuit, to prevent hazards
• resistance can be measured using an ohmmeter
• an ammeter measures the amount of current passing through it
• electrons are negatively charged because opposite charges attract, they draw to the protons.
• voltage is different at points in a parallel circuit because the potential difference is shared between the branches
• if i add more batteries to a circuit, the current will increase
• an insulator is a material that does not allow electricity to flow through it.
• a conductor is a material that allows electricity to flow through it, such as a wire
• copper is a good conductor
• glass is an insulator
• gold/ steel is a conductor
• a rubber band is an insulator
• graphite is an insulator
