Question 1.1)The network of resistances shown above is connected to a 10V D.C. supply. Calculate: a) i) The overall circuit resistance ii) The voltage across each resistor iii) The current flowing through each resistor Construct the network shown above in Multisim and verify your results for part a) i, ii and iii. Evidence should include screen shots of your circuit and measurement results. Answer 1.1) a) ItRt=V∴V÷Rt=It ∴10÷66.7=150mA I1=V÷R4∴10÷100=0.1 I2=It-I1=150mA-100mA=50mA i)1/R2+1/R3=1/300ω+1/300ω=1/.006=150ω 150ω+50ω=200ω ∴ 1/200ω+1/100ω= 1/0.015=66.7ω ii) we use iii’s answers for this so Ix×Rx=Vx R1=.05×50=2.5V R2=.025×300=7.5V R3=.025×300=7.5V R4=0.1×100=100 iii)R4=I1=100mI R1=I2=50mI R2 and 3 are…show more content…
Answer a) Electromagnetic induction is the creation of an electromotive force though a conductor being exposed to magnetic fields on intervals, the creditor of the discovery of faraday’s law of induction is Michael faraday who mathematically described the law. b) One practical use of electromagnetic induction is power generation through a dynamo, which creates an electric charge via Faraday's law of induction. Another practical use of electromagnetic induction is induction welding which uses an induction coil charged with a radio-frequency electric current. This generates a high frequency emf (electromagnetic field) which acts upon a ferromagnetic or conductive workpiece. With the electrically conductive work piece the heat is generated through the resistive heating effect. In ferromagnetic workpieces the heat is created by hysteresis, as the electromagnetic field is continually deforming the ferromagnetic material. __________________________________________________________________________________ Question 4.1 a) A sinusoidal voltage waveform has an R.M.S. value of 10V and a frequency of 100Hz. Calculate: i. The peak voltage ii. The peak-peak
