Answer:
D. a windstorm scratches the surface of a rock with sand.
Answer:
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
Explanation:
Given:
Let the primary voltage be,
Secondary Voltage,
Secondary Resistance,
To Find:
a)
b) I₂ = ?
c) Power = ?
d) R₁ = ?
Solution:
The ratio of primary to secondary turns of the transformer, is the ratio of primary to secondary Voltage and is given by,
Substituting the values we get
For, rms current for the secondary supply,
Substituting the values we get
Now for average power at load,
Substituting the values we get
Now for resistance connected directly across the source line Power will remain same,
Substituting the values we get
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
