Energy, Power, And Resistance

Question 1

Which formula relates voltage and kinetic energy?

Answer 1

eV = 1/2m(v^2)

e - elementary charge - 1.6x10^-19
V - potential difference - V
m - mass - kg
v - speed - m(s^-1)

Question 2

What is the definition of a volt in terms of energy and charge? Give the equation and units

Answer 2

1 volt is the potential difference between 2 points when 1 joule of work is done to move a charge of 1 Coulomb (elementary charge)

V = W/Q

V - potential difference - V
W - energy - J
Q - charge - C
