Question

when a 48 ohm resistor is connected across the terminals of a 6 volt battery of negligible internal resistance,the power developed in the resistor is-- a) 8.0w b) 0.75w c ) 13w d ) 0.125
​

Answer 1

Answer:

option B is the correct answer

Explanation:

p=v^2/R

=36/48=3/4=.075

Answer 2

power = v^2/ r

=> 36/48 = 0.75 w
