Question

Three resistors of resistances 2 ohm,4 ohm and 4 ohm are connected parallel to a 3 v battery .find 1)the equivalent resistance of the combination 2) totap current in the circuit...​

Answer 1

Answer:

4.44v

Explanation:

Equivalent resistance of series combination Req=R1+R2+R3

∴ Req=2+3+4

⟹ Req=9Ω

(b) : Current flowing through the circuit I=ReqE

∴ I=910=1.11 A

Voltage across R1, V1=IR1

∴ V1=1.11×2=2.22 V

Voltage across R2, V2=IR2

∴ V2=1.11×3=3.33 V

Voltage across R3, V3=IR3

∴ V3=1.11×4=4.44 V
