Current Electricity
The flow of electricity
What is Current?
What is the formula for Ohm's Law?
What is Voltage = Current x Resistance? (V = IR)
They have components that get an equal amount of voltage.
What are Parallel circuits?
These temporary magnets are composed of a battery, iron core, and coils of wire.
What are electromagnets?
The effect on the current flowing through a circuit as resistance increases.
What is current decreases?
How much push the flow of electricity has.
What is Voltage?
This voltage produced a current of 50 amps with a resistance of 20 ohms.
What is 1000 Volts?
What is series circuit?
This is an adjustment to the solenoid (coil of wire) which increases the strength of an electromagnet.
What is adding more coils?
This is the unit of measurement for Electric Current.
What is an Ampere (Amp)?
Current only flows in one direction in this type of current.
Direct Current
The current when a 12-volt battery is connected through a resistance of 24 ohms.
What is 0.5 Ω (Ohms)?
This circuit contains four light bulbs. One light bulb goes out but the other three stay lit.
What is Parallel Circuit?
Unlike electromagnets, permanent magnets do not need this in order to be magnetized.
What is electricity (electric current/battery)?
This device converts electrical energy into mechanical energy using magnets, conductors, and a battery.
What is an electric motor?
The opposition to the flow of electric current.
What is resistance?
Silver has a resistance of 0.000198 ohms. This voltage would produce a current of 1000 amps.
The total resistance of a this circuit is equal to the sum of individual resistances.
What is series circuit?
In order for something to be magnetized, this must be true of the domains.
What is aligned?
This device converts mechanical energy into electric energy using magnets, conductors, and a handle/crank.
What is an electric generator?
These two adjustment to a wire increase the resistance of a wire.
What is increasing the length and decreasing the thickness of a wire?
This is the current flowing through a series circuit with two 5 Ω bulbs and one 10 Ω motor, powered by a 25 V wet cell battery.
The sum of the currents through each path is equal to the total current that flows from the source.
What is parallel circuit?
The process of moving a circuit into a magnetic field because when a magnetic field changes, it also changes the electric field.
What is Electromagnetic induction?
This is the astrological sign of your favorite 8th grade Math/Science teacher.
What is Taurus?
