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?
(i) Current through 5 ohm resistor
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
So R= V/I = 6/2 = 3 ohm
(iv) Total V in the given circuit = V1+V2 = 10+6= 16 V
