You have a low voltage lighting system that requires a 24 V RMS source, but all that is available is the 120 V RMS outlet on the wall (frequency of 60 Hz).
- If you make a transformer with the primary coils hooked up to the source voltage and the secondary coils hooked up to the lighting system, how many coils would you design the primary and secondary coils of the transformer to have?
- How would the power dissipated through the primary coils compare to that dissipated at the secondary?
(c) Write an expression for the voltage from the outlet as an expression of time (i) first in generic form without variables filled in, (ii) then with all variables filled in that you can fill in from numbers in the earlier sections of the problem.

Your TV's screen uses 4800 (V) of voltage to operate. To provide 4800 (V), inside your TV there is a transformer that converts wall outlet of 120 (V) to 4800 (V) reaching to the TV screen. The secondary coil of this transformer has 9200 turns. Your TV's screen connected to secondary coil of transformer uses 240 (W) of power. A) Calculate current in secondary coil. B) Is this transformer a step-up or a step-down...

The Lights Q1. Our LED lights are to be powered from a 12 V DC source. Assuming ideal diode characteristics in the rectifier we use and no voltage drops along the wires, what turns ratio N1:N2 is required for a transformer for the lighting subsystem (assume a UK mains system)? The turns ratio required is ? ( 1:20 / 1:10 /20:1 /10:1) [1 mark] Q2. If we have 1000 parking spaces, we have 1000 lights each drawing 20 mA switched...
