Question

class 10 electricity chapter​

Answer 1

hey,

(i) The formula for least count is RANGE/DIVISION

Here range is 1.5 and division is 10

--------> 1.5/10

-------->0.15 V

(ii) The reading shown here is 1.7

(iii) V = IR

 ---> Here V = 1.7 ; R = 20 ohms

-----> by the formula; 1.7 = I x 20

                                  I = 1.7/20

                                  I = 17/200

                                  I = 0.085 A

hope this helps
