A voltage signal of RMS value 220 volts passes through an inductor of value 44 mH. What will be the maximum value of current possible if current changes its direction 50 times in a second? |
16 A 22.5 A 47 A 20 A |
22.5 A |
Vpeak = 1.414 Vrms = 1.414 x 220 V = 311 V Ipeak = Vpeak/wL = 311 V/ (2\(\pi \) x 50 x 44 mH) = 22.5 A |
