Transformer Law

Question 1

V= 30 m/s f=6 ¥=?

Answer 1

¥(wavelength)= v (velocity) / f (frequency )
¥= 30 (v) / 6 (f)
5 m/s

Question 2

V= 20 m/s f= ? ¥= 2m

Answer 2

F (frequency)= 20 m/s (velocity (v)) / 2 m (wavelength)
10 hz
Cause frequency is measured in hz

Question 3

V= ? F= 8 hz ¥= 3m

Answer 3

V (velocity)= 8hz (f) x 3m (wavelength)
24 m/s

Question 4

Electromagnetic
Velocity= frequency x wavelength
Velocity= m/s

Answer 4

Velocity= m/s
Frequency= hz
Wavelength= meters

Question 5

Ohms law
V (volts) = I (current) x R (resistance)

Answer 5

V= Volts
I= amps
Resistance= ohms

Question 6

V= ? I= 3 R= 80

Answer 6

V= 3 (I) x 80 (R)
240 Volts

Question 7

V=110 I= 3 R= ?
We know this will be ohms

Answer 7

R= 110 (volts) / 3 (current)
36.7 or 37 ohms

Question 8

V=110 I=? R=10
We know this will be Amps

Answer 8

I= 110 (v) / 10 (R)
11 amps

Question 9

The secondary coil of a transformer has 10,000 turns and the primary coil has 100 turns.
120 is the volts and amp is 5

Answer 9

10,000 / 100 = 100 to 1 ratio
Step up transformer (voltage increase)
100 x 120= 12000 (increase in volts)
5/100= 0.05 ( decrease in amps)

Question 10

The secondary coil of a transformer has 50,000 turns and the primary coil has 5,000 turns.
120 is the volts and amp is 5

Answer 10

50,000/5,000= 10 to 1 ratio
Step up (volt up Amp down)
120 x 10= 1200 volts (increase)
5/10 = .5 amp (decrease)

Question 11

The secondary coil of a transformer has 500 turns and the primary coil has
10,000 turns.
120 is the volts and amp is 5

Answer 11

500/10,000 = 1 to 20 ratio
Step down
120 volts/ 20 = 6 volts (decrease)
5 x 20= 100 amps (increase)
