New cards
describe the difference between resistance and resistivity
resistance = the specific current oppositions of specific components
resistivity = an electrical property of specific materials
2
New cards
state the relationship between the resistance and the length of a wire
directly proportional
3
New cards
state the relationship between the resistance and the cross-sectional area of a wire
inversely proportional
4
New cards
state the formula for the resistivity of a material
ρ = (RA)/L
resistivity of a material (Ωm) = (resistance of the component (Ω) x cross-sectional area of the component (m²)) / length of the component (m)
