wire has a circulating with four resistors of 4,2,9,6 ohm respectively in parallel find the resistance and draw circuit diagram??? |

Answer» CORRECT option is D 2 and 2 Here, R
=4∣∣4=4/2=2Ω and R 2
=6∣∣6=6/2=3Ω Current in the circuit is I= R 1
+R 2
V
= 2+3 20
=4A As (4∣∣4) and (6∣∣6) are in series so same current I will FLOW through these branches. In parallel branches two RESISTANCES are same so current through each resistance will be I/2=2A |
