The point representing the cut off grid voltage on the mutual characteristic of triode is

The unit of mutual conductance of a triode valve is

Assertion By increasing the accelerationg voltage in coolidge tube wavelength of characteristic X-rays does not change. Reason Cut-off wavelength is inversely proportional to the acceleration voltage
