Time

Answer 2

W J
E J
V V
I A
t S (seconds)

Question 3

Formula to find current

Answer 3

I= w➗VXt

Question 4

Calculating energy and work and power
W and e =
P=

Answer 4

W= I x v x t
P= I x v

Question 5

What way does bc hydro express their energy use

Answer 5

They use hw x hours

kW x hours is a U it of expression for energy “Joules” but simply looks smaller

Question 6

Answer 9

Black hot 120 v
