When a transformer has more secondary windings than primary windings, it?
has a smaller secondary current
has a greater power output
is a step-down transformer
increases the total energy output
Correct answer is A
A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer.
3\(\mu\)F
16\(\mu\)F
24\(\mu\)F
30\(\mu\)F
Correct answer is C
3 = \(\frac{6 \times 8 \times c}{(6 \times 8) + (6 \times c) + (8 \times c}\)
therefore, C = 24\(\mu\)F
N50oE
N40oE
N30oE
N25oE
Correct answer is A
The true declination is calculated by adding the reading of compass bearing to the declination at that place.
= N40°E + 10° = N50°E
