Question

12 resistor is connected in series with a 6 ohm resistor and a 9 v battery sketch the circuit diagram and calculate :
(a) the resistance of the two resistors in series
(b) the current and pd each resistor

Answer 1

A) equivalent resistance = 12+6=18 ohm

B) V=R(eq) I

9=18 I

1/2A=I

I in R1=1/2 A

I in R2=1/2A

V1=R1 I=12x1/2=6 V

V2=R2 I=6x1/2=3 V

Answer 2

Answer:

A) equivalent resistance = 12+6=18 ohm

B) V=R(eq) I

9=18 I

1/2A=I

I in R1=1/2 A

I in R2=1/2A

V1=R1 I=12x1/2=6 V

 

V2=R2 I=6x1/2=3 V
