Batteries
The type of energy a battery stores and converts into electrical energy.
What is chemical energy?
Every magnet has these two poles.
What is a north and south pole?
This is the electrical charged carried by electrons that surround a nucleus.
What is negative charge?
This unit measures the amount of electric current flowing through a circuit.
What are amps?
This tool can measure the amount of current, in amps, flowing through a circuit.
What is a Multimeter?
Unlike the current from our home outlets, this type of current comes from a battery.
What is DC?
When electric current flows through a wire, it also produces this around the wire.
What is a magnetic field?
The number of these particles in an atom's nucleus determines which element it is.
What is a proton?
This unit measures the electrical potential difference, or the “push,” that drives current through a circuit.
What are volts?
In a circuit diagram, a circle with the letter “M” inside represents this component.
What is a motor?
A battery reaches this state when electrons can no longer move through a circuit.
What is a dead battery?
Moving a magnet back and forth through a coil of wire creates this type of current, which keeps switching direction.
What is Alternating Current?
This tiny particle is responsible for most of the action in circuits, but it weighs far less than a proton.
What is an electron?
This law describes the relationship between voltage, current, and resistance in an electrical circuit.
What is Ohm's Law?
In electricity, this is represented by a solid line with a dashed line underneath.
What is Direct Current?
Common household batteries are made of made of zinc and manganese dioxide, but ions of this element are often used in rechargeable batteries like laptops, smartphones, and electric cars.
What is Lithium?
This device uses electrical energy and magnetism to produce mechanical energy.
What is a motor?
These electrons are found in the outermost energy level and play a major role in how atoms bond and conduct electricity.
What are valence electrons?
This is represented by the omega symbol "Ω" and measured in ohms.
What is resistance?
This component turns electrical energy into visible light.
What is a lightbulb or LED?
When connected in this way, batteries add their voltages together to provide more voltage to a circuit.
What is in series?
This device uses motion and magnetism to produce electrical energy.
What is a generator?
This term describes an atom that has gained or lost electrons and therefore has an electrical charge.
What is an ion?
If a circuit has a resistance of 6 Ω and a voltage of 12 V, this is the amount of current flowing through it.
What is 2 amps?
This type of circuit allows electricity to flow from the power source through components.
What is a closed circuit?
