Question

when a 12 v battery is connected across an unknown resistors there is a current 2.5 ma in circuit it. find the value of the resistance of resistors ​

Answer 1

We have potential difference (V) = 12V

Electric current (I)=2.5 mA= 2.4×10-3

According to Ohm’s Law (V) = IR

Or R = V/I

Answer 2

Answer:

v=ir

Explanation:

so

12=250*r

r=12/250

r=0.48
