Q. 1 B4.4( 14 Votes )

Two resistances are connected in series as shown in the diagram:



(i) What is the current through the 5 ohm resistance?

(ii) What is the current through R?

(iii) What is the value of R?

(iv) What is the value of V?

Answer :

(i) Current through 5 ohm resistor

I= V/R


I = 10/5 = 2A


(ii) Two resistances are connected in series. So same current flow through the circuit,


So current flowing through R =2A


(iii) As we know that according to ohm's law


V=IR


So R= V/I = 6/2 = 3 ohm


(iv) Total V in the given circuit = V1+V2 = 10+6= 16 V
