Five resistors are connected in a circuit as shown. Find the ammeter reading when circuit is closed. |
|
Answer» SOLUTION :The resistance between the POINTS B and D is x `x= (3Omegaxx6 Omega)/(3 Omega+6Omega) = 2 Omega` Now the resistance of the whole combination is ` R= 0.5 Omega+x + 0.5 Omega` `= 0.5 Omega +2.0 Omega + 0.5 Omega` `:.` Ammeter READING `= (3V)/(3Omega)` = 1.0 AMPERE. |
