Physics Flashcards
Opposite charges attract and same charges repel
Law of charges
An example of law of charges is?
Magnets or Rubbing balloon on hair
It is how strong is the force of a charge
Electric Field Strength
Used to measure the point charge
Test charge
Electric is kinetic energy but how it is called electric potential energy?
Its potential since its stored
What type of charges flow in batteries?
Negative charges
It is also known as the electric potential difference
Voltage
A flow of charged particles
Current
Is the measure of the opposition of flow of charges
Resistance
The current in circuit is directly proportional to the voltage and inversely proportional to the resistance
Ohm’s Law
Amount of work done over time
Power
Is a closed loop in which electricity flow?
Circuit
1 pathway circuit
Series Circuit
It is known as the circuit breaker
Fuse
It is known as the light bulb
Load
Its a circuit with multiple pathway
Parallel Circuit
It is known as the battery in a circuit
Source
It is known as the pathway of a circuit
Wire
Why copper is a good conductor?
It is ductile and can be turned into wires
Can water be a conductor?
Yes
Why do you need to control the charge?
They have specific capacities
What does short circuit means?
Too much load
Why does electricity have a range
Electricity is not steady rather its fluctuating
How to increase the flow of charge
Increase the voltage
If one increase, the other increases
Directly Proportional
If one increase the other decreases
Inversely Proportional
It produces energy and displacement is important
Work
Is used to move something
Energy
Unit of power
Watts
Why inverters are cheap?
It lowers the consumption to maintain its temperature
Circuit comes to a latin word
Circum
Circum means
It circulates or around
Circuit board has no wire because its made up of?
Copper
What happens to the pathway if the switch is closed
It opens the circuit
What happens to the circuit if the switch is open
It has no pathway
A Christmas light went off when you cut off a wire what circuit does it have?
Series
If you cut one wire and the circuit still works then what type of circuit is it?
Parallel Circuit
The lamp was switched to the off button, is the switch open or closed.
Open
A device that controls the flow of current in the circuit
Switch
Why horsepower is used
Horsepower is commonly used to measure the power of engines and motors
