Answer:
Turns ratio=108, Pin= 110.5 W, Current ratting= 920mA
Explanation:
Vp=120 V(rms)
Vs=13,000 V (rms)
Is = 8.50*10^-3 V(rms)
a.
secondary to primary turn ration:
Ns/Np=Vs/Vp
=
=
= 108
b.
Is=8.50 mA (rms)
As Vs= 13,000V (rms)
For ideal transformer
Pin=Pout______(1)
Pout= Is*Vs (put in equ 1)
Pi=Is*Vs
Pi=(8.50*10^-3)*(13,000) W
Pi=110.5 W
Power supplied will be 110.5 W.
c.
We have to find the current passing through primary circuit to find current rating of fuse in primary circuit.
For ideal case
Ip*Vp= Is*Vs
Ip=
Ip= (13000*8.5*10^-3)/120
Ip=920 mA
In primary circuit fuse current rating will be 920 mA.
Marbles would have the greater density. Marbles would have the greater density because the molecules inside are more tightly packed. Even though sand has the greater mass it does not have the greater density. The sand doesn't have the greater density because it could be crushed in an instant, showing that if molecules are packed together tightly they will be tougher to break. The dice, I believe, still have a greater density than the sand.
Explanation:
some objects that are conduct :Metals conduct electricity, so if there is just the symbol of a metal, eg Mg(s), then it will conduct, even in the solid or liquid state. 2. Ionic compounds conduct when they are dissolved in water, or are melted.
what can it do ?:
A conductor is a material which electricity, heat or sound can flow through. An electrical conductor conducts electricity. ... This means that they make it very hard for electricity to flow through them. A material that stops electric current is called an insulator (electricity).
hope this helped! if not I'll answer again
Angular velocity w is directly proportional to its velocity.
