Find the following for an input of 120 vac(rms), 60 hertz, given a 10: 1 stepdown transformer, and a full-wave bridge rectifier. rload is 50 ohms. round off to the nearest tenths place. i. primary or input peak voltage ii. secondary peak voltage iii. peak voltage out of the rectifier iv. dc voltage out of the rectifier v. dc current into the load

(i) 169.68 volt

(ii) 16.90 volt

(iii) 16.90 volt

(iv) 108.07 volt

(v) 2.161 A

Explanation:

Turn ratio is given as 10:1

We have given that input voltage

(i) We know that peak voltage is give by

(ii) We know that for transformer

So

So peak voltage in secondary will be 16.90 volt

(iii) Peak voltage of the rectifier will be equal to the peak voltage of the secondary

So peak voltage of the rectifier will be 16.90 volt

(iv) Dc voltage of the rectifier is given by

(v) Now dc current is given by

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

i dont know the answer but good luck
