For this case we have the following equation:
V = I * R
Where,
V: voltage
I: current
R: resistance
By clearing R we have:
R = V / I
Substituting the values:
R = (20) / (0.57)
R = 35.09 Ohms
Answer:
The resistance of the light bulb is:
R = 35.09 Ohms
Draw the triangle and then use Pythagoras' theorem
distance =
= 19.70 (2dp)
Yea you got this the answer is easy
I THINK THE ANSWER IS...
