Formulas and Key Relations

Electric Current and Charge Flow

i=Q/t

Q=ne, i=ne/t

Electric Potential and Potential Difference

V=W/Q

1 volt = 1 joule/1 coulomb

Resistance and Ohm's Law

V=iR

R=V/i

R=(V2-V1)/(i2-i1)=ΔV/Δi

Conductance: σ=1/R

Factors Affecting Resistance and Resistivity

R=ρl/A

ρ=RA/l

σ=1/ρ

Formula

i=Q/t.

1 ampere = 1 coulomb per second.
