1
Q
what is the equation for the current
A
I=Q/t
2
Q
what is the equation for voltz
A
V(E)=W/Q
3
Q
what is the equation for resistance
A
R=V/I
4
Q
what is the equation for power
A
P=I times V
5
Q
what is the equation for energy
A
I times V times T
6
Q
what unit should time always be in
A
seconds
7
Q
what is voltage also know as
A
Potential difference
8
Q
why do voltage current graphs with non linear( non ohmic) subjects curve at the top
A
becuase the lamps heat up; more collisions occur between electrons and that causes more resistance.
