how did you calculate that? Assuming resistor is 18 ohms (most likely higher),
P = I^2 * R
P = 0.06A * 0.06A * 18 = 0.0648 W = 64.8mW
64.8mW is burned through the resistor itself.

Don't worry about checking my work, i'm not studying electrical engineering for nothing. Everything electrical i've got no problems with, it's when it comes to the mechanical stuff I'm no good with
