SORRY:(
I have actually again missed 1 word in part a of the Q, so I am writing it again:
a) What is the output power of the transformer?
b) Given: V primary = 120V
N primary 1200 turns
V secondary 6 v
Required: n secondary
Analysis: V1 N2= V2 N1
N2= V2*...
HI! Here is the exact word-to-word problem:
Q3: A samll transformer with 1200 turns in the primary coil is used to power a portable tape player that has an output current of 300 mA and an output voltage of 6.0V. The label on the transformer says that the input is 5W at 120V, if there were 1200...
OMG! I missed the part of the Q, Here is the it:
"a appliance that has an output curret of 300mA & an output voltage of 6V. The label on the transformer says that the input is 5W at 120V. What will be the output power of the transformer? "
I revised it :
Given: V output= 0.6*10V (6V)
I output= 300 mA or (300*10^-3)
Required: P Output
Analysis: P=IV
Solution: 300*10^-3A *0.6*10V
= 1.8W will be the output power of the transformer?
is this correct?
Transformer HELP!
A small transformer with 1200 turns In the primary coil is used to power a appliance that has a output voltage of 6V. The label o the transformer says that the input is 5W at 120V. What will be the output power of the transformer?
Given: V output= 0.6*10V (6V)...
Given: f= 1445 Hz.
Length= 0.36m (36 cm is converted)
Required: v and vs
Analysis: v=f(lambda)
Solution:
Lambda=2l/n
=2(.36m)3
=0.24m
v= (1445Hz)(0.24)
V= 346.8m/s
Now we can find the temperature:
Analysis: T= vs-332m/s
0.60...
Given: f= 1445 Hz.
Lambda= 0.36m (36 cm is converted)
Required: v and vs
Analysis: v=f(lambda)
Solution: v= (1445Hz)(0.36)
V= 520.2m/s
Now we can find the temperature:
Analysis: T= vs-332m/s
0.60
= 520.2-332/0.6...
Hi!
Q: A column of air length 36cm is closed at both ends, resonates to as sound of third lowest frequceny of 1445Hz. Calculate the air temperature given that the reasonable temperature falls between 10 and 20 C??
Here is what I tried:
Given T= 20 ( 30-10= 20)
Required: vs & T...
