- The core shown in Figure P1-2 has the flux o shown in Figure P1-12. Sketch the voltage present at the terminals of the coil. -10cm- 20cm— 500 tons 15 cm Core depth = 5 cm 0.010---- 0.005 (ms) -0.005 -0.010---

Answer 1

Answer: - Given Refer to figure 1-2 and 1-12 'in the textbook, -> foom the faradays law s electporna gentres induction, the EMF induced in the coil is, where N-number & turng do= change in flux e and an ad 0 MEN dt change in time. - the figure 1-12, cakulak the induced EMF in the lonductor at different instants. S : At in stent (O <tezlms! the change in flux in from oub to o.ol wb dd -0.01 wb-owb the -0.01wb change in time is , dt =gms-oms -θης The EMF induced in the conduction during this instant is end, = (sooterms) a mente) = (500) cs)v ca. Skv. Note: the flux wave is raising in positive direction the induced EMF also positive a): At instant (actes) The change in flux is from ool wb too olub do = -oolwb-0.01wb =-0.02wb

@ The change in time is, dt= sms.ams -3ms The EMF induced in the contuctor during this instant is, efnd 2 = (soo forms) (-o s) endza (5001 46.6) 2-3.3 kV the induced Note: The flux is increasing in negative drection EMF also negative. =>:: At instant (sct) ms. the change in flux is from nool wb to owb. !. do rowb-fo.olwb) roolwb And change in time is dt=7ms sms -ams. .. The EMF induced in the conductor during this instant's pind 4 = (soo turno) Comentario = (500) (50) - 2.5kv. Note: the flux wave is raising in positive direction in induced Emf also positive. =) At in stant at colms the change in flux is from owb to ool wb do -0.01ab-owb = 0 olub

during this instant is, And change in time is, dt-sms-oms =lms The EMI induced in the conductor ende = (500 turns) (olub) ( Soo) golv - skv also Positive the Emf direction induced - id positive Draw the wave form of the induced Voltage, prot blw voltage and time induced Voltage kv) en &nd-oi ? n & i 2 ² 4 Ã 4 Time (ms)
