Go with the Flow: Current Electricity
What is a conductor?
A continuous unbroken path through which electricity can flow.
What is a circuit?
This works as a result of a chemical reaction and movement of electrons.
What is a battery?
This is the ability a material has to attract iron.
What is a magnet?
Discovered that current traveling through a wire produces a weak magnetic field in the live wire.
Material that does now allow electricity to flow through it.
What is an insulator?
This has one path for electricity to flow. If the path has a break at any point, it cannot complete the circuit.
What is a series circuit?
This battery is less likely to expose hazardous electrolytes. It can be used in any position and is easy to use.
What is a dry-cell battery?
Magnets and static electricity act in some similar ways. This is one.
What is they attract and repel other objects?
Both discovered that a moving magnet around or through a loop of wire produces electricty in the wire.
This will stop electricity from flowing easily as the electrons have to push harder to get through.
What is a resistor?
This has multiple paths for electricity to flow. If a bulb burns out, it breaks only the one circuit.
What is a parallel circuit?
The unit that measure power, or how fast work is done.
What is a watt?
A coil of wire with a core attached to an electrical source.
What is an electromagnet?
Moving a magnet around or through a loop of wire produces electricity in the wire. Moving a wire between the north and south poles of two magnets also produce electricity in the wire.
How does magnetism produce electricity?
This machine uses a magnet to convert motion into electrical energy.
What is a generator?
This is a conductor that can be moved to bridge the gap or not bridge the gap in a circuit.
What is a switch?
This is the unit that measures the amount of electrical push, or force, in a circuit.
What is an volt?
An area of magnetic force around a magnet.
What is a magnetic field?
Explin why buildings have electrical wiring arranged in parallel rather than series circuits.
If the wiring of an entire building is on a series circuit, every time a break in the circuit occured, every electrical device would stop working. A problem in a series circuit is harder to find than one in a parallel circuit.
A liquid or paste substance that conducts electricity.
What is an electrolyte?
This is a very small circuit with all the parts built into it.
What is a integrated circuit?
This shows how much current flows through a given part of a circuit in one second.
What is an ampere?
The movement of a magnet around or through a loop of wire will produce this.
What is electricity?
If someone has fallen onto a high voltage electric fence and is getting shocked, would it be safer for rescue workers to use a metal pole or a wooden stick to pull him away from the fence? Explain.
The wooden stick would be safer. Metal is a conductor and would allow the electricity to flow to the rescue worker. Wood is an insulator.
