All about circuits
What is a series circuit?
(A closed loop in which the current follows one single path)
Whats used to measure voltage?
(Voltmeter or multimeter)
what is the law of conservation of charge?
( in a closed system, the total amount of electric charge remains constant; it cannot be created or destroyed, only transferred. )
Ohm's law
(V=IR)
Who discovered electricity?
( Ben Frank, Michael faraday)
What is a parallel circuit?
(electrical circuit where components are connected across the same two points, creating multiple paths for current to flow, meaning that if one component fails, the others can still function.)
what is current measured in?
(Amps)
what are the four fundamental forces?
( Gravity, Weak nuclear force, Electromagnetism,strong nuclear force)
how do you find the total resistance of a series circuit?
(For series circuits, add the resistances)
Is rubber a good conductor of electricity?
(Yes)
What is a open circuit?
(an electrical circuit where the path for current flow is broken or interrupted, preventing electricity from flowing.)
what is the unit of resistance?
(Ohm)
What is the difference between electrostatic and gravitational forces?
(Electrostatic force, or Coulomb force, acts between charged objects and can be attractive or repulsive, while gravitational force acts between objects with mass and is always attractive)
how do you find the total resistance of a parallel circuit?
( for parallel circuits, use the reciprocal formula (1/Rt = 1/R1 + 1/R2 + ... )
After rubbing a balloon with a towel, Why does it stick?
(static electricity)
:When a closed parallel circuit when the path divides into two or more paths does each path receive the same amount of voltage?
Yes, in a closed parallel circuit, each path (or branch) receives the same amount of voltage.
What is a conductor?
(electrons can easily move through)
How do you find electric potential?
( potential charge of multiple charges)
Formula for columbs law?
(F=k|q1q2|r2.) (electric force=k charge1 and charge 2 divided by distances of separation)
Is current the same throughout a series circuit?
Yes, in a series circuit, the current is the same throughout the entire circuit.
