Answer:
26 V
Explanation:
Given:
The three resistors 5.5 V. 8.2 V. and 12,3 V. are connected in series.
Now we have to find out the source voltage to which these resistors arc connected ?
Solution:
As we know in series the magnitude of current is uniform but the voltage divides between the resistors supplied from source voltage.So the magnitude of source voltage is, 5.5 V + 8.2 V + 12.3 V = 26 V
Hence, the value of the source voltage to which these resistors are connected is 26 V
Answer:
option (b)
Explanation:
for a telescope, the object is placed very far from the objective lens so the focal length of objective is large and the eye piece is of short focal length.
So, long focal length objective and short focal length eyepiece.
Option (b) is correct.
