1) 1 240H is equivalent to a ????? inductor(mH) 2)THE VOLTAGE ACROSS A COIL WHEN DI/DT = 20 ma/sand L = 8H is ?????? 16mV,160MV,1.6MV OR 2.5 MV??? 3) an 18 v power supply is connected across a coil with awinding resistance of 180.current flow in the coil is? 4)the following coils are in parallel : 75,40,25,and 15 (allH).The total inductance is approx?? 1) 1 240H is equivalent to a ????? inductor(mH) 2)THE VOLTAGE ACROSS A COIL WHEN DI/DT = 20 ma/sand L = 8H is ?????? 16mV,160MV,1.6MV OR 2.5 MV??? 3) an 18 v power supply is connected across a coil with awinding resistance of 180.current flow in the coil is? 4)the following coils are in parallel : 75,40,25,and 15 (allH).The total inductance is approx??Explanation / Answer
1240H =1240 * 0.001 mH = 1.24mH V = Ldi/dt therefore 20ma/S = 20 KA/s , V = 20K*8 =160mV V= IR I =V/r = 18/180 = 0.1A 1/L = 1/l1 + 1/l2+ 1/l3 + 1/l4 = (1/75 + 1/40 + 1/25 +1/15)*1/1 L =6.896H
