What is the equation that links voltage current and resistance?
V = I / R
V = I x R
V = R / I
V x R = I
What is the equation that links voltage charge and energy?
V = E / Q
V = Q x E
V = Q / E
V x E = Q
What is the equation that links current charge and time?
I = t / Q
I = Q x t
I = Q / t
I x Q = t
What is the equation that links force mass and acceleration?
F = m / a
F = m x a
F = a / m
F x a = m
