Question

Question 5 a) A transformer has 500 turns on the primary and 1500 turns on the secondary. If the output voltage is 36 V what is the input voltage? What type of transformer is this? (3 marks) b) 100 kW is delivered to a town along power lines that have a total resistance of 0.4 0. Calculate the power loss if the electricity is delivered at a voltage of () 240 V and (ii) 24kV. (5 marks) c) If the collector current of a transistor is 0.3 amps and the base current is 0.001 amps, what is the current gain? (2 marks) Total 10 marks Space to answer Question 5 here

please, answer all the questions

Answer 1

al Vs Vp given Vs = 36v so Up As 500 AP XVs 36 17 Up 12V Since Vp < Vs hence Step up toms form (b) power loss. p. R.

for the last question u need to perform the experiment with thermistor wire and plot graph same as I draw

Rest are calculated

Plz do like I Badly need plz do it
