Question
Chapter 25, Problem 59A
(a)
To determine
To calculate:
Turns ratio of transformer
(a)
Expert Solution
Answer to Problem 59A
Turns ratio the transformer would have is 2.01.0
Explanation of Solution
Given:
Vs=120 V
Vp=240 V
Formula used:
NpNs=VpVs
where,
Vs = effective potential difference of secondary coil
Np = No of turns of primary coil
Vp = effective potential difference of primary coil
Ns = No of turns of secondary coil
Calculation:
Turns ratio the transformer would have can be calculated by the ratio,
NpNs=VpVs
Substituting the values in above ratio,
= 2.01.0
That is from 2.0:1.0
Conclusion:
Hence turns ratio the transformer would have is 
(b)
To determine
To calculate:
Current drawn by the hair dryer from 240 V line.
(b)
Expert Solution
Answer to Problem 59A
Current drawn by the hair dryer from 240V line is 5 A
Explanation of Solution
Given:
Is=10 A
Vs=120 V
Vp=240 V
Formula used:
VpIp=VsIs
where,
Vs = effective potential difference of secondary coil
Np = No of turns of primary coil
Vp = effective potential difference of primary coil
Ns = No of turns of secondary coil
Ip = current of secondary coil
Calculation:
Current drawn by the hair dryer from 240V line can be given by the formula,
VpIp=VsIs
Rearranging the equation ,
Ip=VsIsVp
Substitutitng the values in the above formula,
=(120)(10)240
=5 A
Conclusion:
Hence current drawn by the hair dryer from 240V line is =5 A
