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.
A battery of emf \( E \) and internal resistance \( r \) is connected to a rheostat. When a current of 2A is drawn from the battery, the potential difference across the rheostat is 5V. The potential difference becomes 4V when a current of 4A is drawn from the battery. Calculate the value of \( E \) and \( r \).
