Question 9
In a CRT, electrons are accelerated through a potential difference of 10,000 V over a distance of 40 mm per minute ________ W is the average power supplied to the beam of electrons.
Question 10
A single range potentiometer has a 18 step dial switch where each step-represents 0.1 V. The dial resistors are 10 Ω. The slide wire of the potentiometer is circular and has 11 turns and a resistance of 11 Ω each. The slide wire has 100 divisions and interpolation can be done to one fourth of a division. The working battery has a voltage of 6 V and negligible internal resistance then the resolution of instrument is
