Question

I want the solution of question 21 all parts... please help as fast as possible...

Answer 1

Hi friend,

1) since two resistors are in parallel,

Effective resistance= R1+R2

R= 8+8

R= 16 ohm.

2)according to ohm's law,

V= IR

I= V/R

I=8/4
I= 2A

3)v= ir

V= 2×4

V= 8V

4)power(P)= I²R

P= 2²×4

P= 16W

5)I think there is ammeter difference in reading as the both resistors having different current.

I=2-1

I= 1A

Hope this helped you a little!!!
