Electrical Systems Flashcards
How is current proportional to voltage
Current is directly proportional to voltage meaning that if current increases, so does voltage. When you double the voltage, the current will double.
Formula for voltage
current x resistance
Function of voltage in a circuit
It is the pressure from the power source that pushes the electrons to move around
Relationship between current and resistance
Current is inversely proportional to resistance meaning that if current is increased by 2 resistance will decrease by 2 and vice versa
When voltage is introduced, what happens to the direction of current
, It flows in one direction
Voltage is also known as
Electrical Potential Difference
What is static electricity and how is it generated?
Static electricity is an electrical charge that builds up on the surface of an object. It is generated through the transfer of electrons between two materials that are rubbed together, such as clothing and skin, or a balloon and hair.
How does the concept of positive and negative charges relate to static electricity?
Positive and negative charges are fundamental to static electricity. When two materials are rubbed together, electrons are transferred from one surface to the other. The surface that loses electrons becomes positively charged, while the surface that gains electrons becomes negatively charged.
What is the role of friction in generating static electricity?
When two dissimilar materials are rubbed together, the friction causes electrons to be transferred from one surface to the other. This results in one surface becoming positively charged and the other becoming negatively charged, creating a static electricity buildup.
What particles moves in the process of static electricity
Electrons
What force is used during static electricity
Electrostatic force
If the magnitude of one charge is doubled while the other charge remains the same, how will the electrostatic force change? Eg. 2 is doubled while 1 is kept the same
If the magnitude of one charge is doubled while the other remains the same, the electrostatic force will also double in magnitude.
If the magnitudes of both charges are tripled, how will the electrostatic force change?
If the magnitudes of both charges are tripled, the electrostatic force will increase by a factor of 9 (3 x 3 = 9), since the force is directly proportional to the product of the charge magnitudes.
