Resistance and Resistivity Flashcards
1
Q
What is the definition of resistance/what is it measured in?
A
The difficulty of getting a current to flow through a circuit Measured in ohms.
2
Q
What is the equation for resistance?
A
R(resistance) = V(voltage)/I(current)
3
Q
What is resistivity?
A
Resistivity is defined as the resistance of a 1mm length and 1m^2 cross sectional area of a material in ohms/meter.
4
Q
What is the equation of resistance using resistivity?
A
R(resistance) = p(rho, resistivity) x L(length)/A(area)
