For the circuit shown above, the equivalent gate is:
Looking at the circuit: - The circuit consists of two gates: an AND gate and a NOT gate (in the form of an inverter).
- The inputs \( A \) and \( B \) are first passed through the AND gate.
- The output of the AND gate is then passed through a NOT gate (inverter). This combination of an AND gate followed by a NOT gate is equivalent to a NAND gate, as the NAND gate is the negation of the AND gate. Thus, the equivalent gate is a NAND gate.

The equivalent resistance between the points \(A\) and \(B\) in the given circuit is \[ \frac{x}{5}\,\Omega. \] Find the value of \(x\). 
A Wheatstone bridge is initially at room temperature and all arms of the bridge have same value of resistances \[ (R_1=R_2=R_3=R_4). \] When \(R_3\) resistance is heated, its resistance value increases by \(10%\). The potential difference \((V_a-V_b)\) after \(R_3\) is heated is _______ V.
