4. Hydraulic systems are fire proof.

Assertion (A): JFET is a voltage controlled device.

Reason (R): The drain current can be controlled by controlling V_GS.

Assertion (A): To add 8 bit words, two 1C 74181 can be cascaded.

Reason (R): In 1C 74181 a sum greater than 15 leads to high carry out.

Assertion (A): The s domain impedance of a series R-L circuit is R + sL irrespective of initial conditions.

Reason (R): Complex frequency s = σ + jω.

1. An integer constant must have at least one digit.
2. An integer constant must not have a decimal point.
3. An integer constant may be positive or negative.
4. The default sign is positive.
5. A maximum of one comma or blank is allowed.

Assertion (A): A JFET behaves as a resistor when V_GS < V_P.

Reason (R): When V_GS < V_P, the drain current in a JFET is almost constant.
