Question

if the current through 1ohm resistor is 2A,the ammeter reading is​

Answer 1

Answer:

The equivalent resistance for resistors 3 and 6 is R

36

=

3+6

3×6

=2Ω and voltage across it =IR

36

=2×2=4V.

Thus, voltage across R =6−4=2V and as the current 2 A passes through R so R=V/I=2/2=1 ohm.
