Question

3) If a 12V battery is connected in
series with resistors 3ohm 4 ohm and 5ohm, then the current flows through the 3 ohm resistor.
a) I A b 2A () 3A d) AA.​

Answer 1

Answer:

d) 4 A

Explanation:

we know that ,V=IR

I=V/R

I=12 /3

I =4 amphere

Answer 2

Answer:

Explanation:

R1=3 Ohm

R2=4 ohm

R3= 5 ohm

R(eq)= R1+ R2+R3

=3+4+5

=12 ohm

now, v=12v

v=iR(eq)

12=i*12

i=1amp

as all res. are in series hence current is same for all , so current flowing through 3 ohm resistor is 1 ampere
