1830
1
"Conservation of charge" ..what does it means?
Charge Cannot be created or destroyed only transferred from one object to another
1

•_______ -Always in series
Start from the smallest calibration and
Voltage
Resistance
Current
1
When an electric current is passed through a coil of wire wrapped around a metal core, a very strong magnetic field is produced. This is called an__________
Electromagnet.
2
How many atoms makes 10 cm of an object?
Around 10 billion.
2
What is 1C charge equivalent to?
6.24 x 10 to the power of 18
2
Magnetic energy moves from __pole to __pole
North to South
2
In a series circuit with 3 resistors the total voltage will be ____ . Total Resistance will be _____ and Total Current will be _____.
V=V1+V2+V3
R=R1+R2+R3
Current will be I same current flows through all resistors.
2
As the number of coils _____ the electromagnet strength increases
increases.
3
What causes subatomic particle to get loose and charge an object negatively?
Friction & Heat causes the electrons to drop and charge an object.
3
What is an Electric Field?
electric field is generated by electric charge and tells us the force per unit charge at all locations in space around a charge.
3
In a battery your turn _____ energy to electrical enerygy
Chemical Energy.
3
Current can flow easily through a thin wire or thick wire at low frequencies?
Thick wire because area of a thick wire is more
3
Electromagnet strength depends on these two factors
•Number of coils
•Current (controlled by voltage and resistance of wires in circuit)
4
What is static electricity?
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge.
4
____ is when the electric field in a wave causes the particles in a material to shift slightly resulting in separation of center of positive charge and the center of negative charge in a material.
Polarization
4
Explain Ohm's Law
V=IR
says that the bigger the push (voltage), the more electricity flows (current) through a pathway, but the harder it is to flow if the pathway is bumpy (resistance).
4
A capacitor uses the principal of _________ to get charged
Induction
4
In a parallel circuit the Voltage across each resistor is ____
same
5
What does colulomb explains in his law?
F=KqQ/F^2
1.
If the charges are bigger (more positive or negative), the force will be stronger.
2.
If the objects are closer together, the force will be stronger.
3.
If the objects are farther apart, the force will be weaker.
5
On Earth which direction is magnetic North & Magnetic South?
North pole is magnetic south and south pole is magnetic North.
5
In a Complete Circuit electrons flow from _______terminal of the battery to ____ terminal of the battery
In a complete circuit, the electrons flow from the negative terminal of the battery to the positive terminal. It looks like a positive charge is moving in the other direction, but actually, the positive particles stay still.
5
In Flemings left hand rule what does the thumb shows.
Motion.
5
In this type of circuit if one component breaks down the whole circuit will burn out.
series circuit
