Question about voltage
(1/1)
DoorVb:
The formula for voltage is V(volt) = J(joule) / C(coulomb)

Does this mean that if I have a resistor that is dropping one volt, every coulomb of charge that passes trough it generates one joule of heat?

Or am I getting the formula wrong?

Any help is appreciated, :)

Paul Rose:
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.
