Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps
Answer:
A)
p1 (0,0) p2 (1,2) given from the graph
slope = (y2-y1)/ (x2-x1 )
slope (m) = 2
y = mx+ b
b =0
y = 2x
b)
x = 0
y = 5
(0,5)
C)
gradient = slope
y = 3x + b
point given (0,12)
y = 3x + 12
Answer: 6
Step-by-step explanation:
6 x 3 = 18
