Electrostatics and Circuits Flashcards
Explain electrical conductivity.
physical property that describes how easily electric charge flows through a given material.
What are electrical conductors?
Facilitate electrical current usually metals
What are electrical insulators?
inhibit electrical current, usually nonmetals
Write the equation for total capacitance of capacitors arranged in PARALLEL.
Write the equation for total capacitance of capacitors arranged in SERIES.
Write the equation for Ohms Law.
Voltage is equal to the product of resistance R and current I
V = I x R
Write the equation for total resistance of resistors arranged in SERIES.
Write the equation for total resistance of resistors arranged in PARALLEL.
Explain what is capacitance.
Ability of a capacitor to store electric charge
Measure in farads (F)
Write the equation of energy in a capacitor that is stored.
Write the equation for electric power.
Write the equation for electric current.
Describe what happens when electric charges with the same sign/different sign come together.
Electric charges with the same sign repel each other and charges with opposite signs attract
Describe the relationship between cross sectional area and resistance.
If a resistor cross sectional area is doubled, its resistance will cut in half.
thus, it will be an inverse relationship.
Describe the relationship between electrical potential and distance from the source charge.
electrical potential is inversely proportional to the distance from the source charge
