Sounds right to me.
I used to thinking of it in terms of power and current.
P = I * V
1 Ampere dropping 1 Volt = 1 Watt of power
That 1 Ampere is just 1 Coulomb of charge per second. And that 1 watt is just 1 Joule per second.
Substitute power with charge per time, substitute current with charge per second. Same story.
