5.Determine the current in the primary.

6.A transformer is said to be ideal if the power developed across the primary equals the power developed across the secondary. Assuming the transformer used in this question is ideal, find the power (P=IV) developed across either the primary or secondary.

What is the direction (a-I) of the magnetic force on a positive charge at location 2 (marked with an x)? Correct answer not given zero into the page out of the page. What is the direction (a-I) of the magnetic field of the bar magnet at location 2 (marked with an x)? Correct answer not given out of the page into the page zero

Explanation / Answer

Np=Primary turn

Ns=Secondary turn

Vp=primary volytagr

Vs=Secondary voltage

Is=Secondarycurrent

Ip=Primary current

Transformer Equation is K=Vp/Vs=Np/Ns=Is/Ip

If Np>Ns it is step down,If Np<Ns step up,Np=Ns ,isolation transformer

Answers

Q1.Stepdown

Q2=12volts/1000ohms =0.001Amps

Q3= Stepdown transformer

Q4=50,Apply Equation of K

Q5 Ip=0.6/50=0.012,Apply Eqation K
