# Q = It watch

1. Are charge and current directly proportional?

Charge and current are, due to Q = It, but idk about the second one, I'm only GCSE
3. Also yes to the second
Also yes to the second
Is there some kind of equation to show their proportional relationship? Thanks!

I got a Grade 8 in my Physics mock!!!

Current is just the rate of flow of charge (electrons) , which means how fast 1 Coulomb of electrons pass through a point in 1 second. The more charge you passes through,the more the current increases.
( By the way, 1 Coulomb of charge contains 6.2x10^18 electrons)
7. Yeah, irradiance is just the power per unit area.
I=P/(4*pi*r^2)
For a spherical source.
