In the circuit diagram shown,each battery is ideal having an e.m.f. of $1\ V$. Each resistor has a resistance of $1\ \Omega$. The ammeter $(A)$ has a resistance of $1\ \Omega$. Find the reading of the ammeter and the total thermal power produced in the circuit.

  • A
    $1\ A, 22\ W$
  • B
    $1\ A, 44\ W$
  • C
    $1/2\ A, 11\ W$
  • D
    $2\ A, 88\ W$
