In an experiment, the saturation in the plate current in a diode is observed at 240V. But a student still wants to increase the plate current. It can be done, if
|
(a) The plate voltage is increased further |
|
(b) The plate voltage is decreased |
|
(c) The filament current is decreased |
|
(d) The filament current is increased |
Assertion : The resistance of super-conductor is zero.
Reason : The super-conductors are used for the transmission of electric power.
|
(a) If both assertion and reason are true and the reason is the correct explanation of the assertion. |
|
(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. |
|
(c) If assertion is true but reason is false. |
|
(d) If the assertion and reason both are false. |
