# A p.d. of 4 V is

Answer :

(a) When two resistors are connected in series, their resultant resistance is given by

R= R1+R2

Here R1 = 6 ohm

R2= 2 ohm

Combined resistance, R = R1 + R2 = 6+2 = 8 ohm

(b) We know that the current, I= V/R

Here R = 8 ohm

V= 4V

I = 4/8 = 0.5 amp

(c) Potential difference across 6ohm resistor V= I x R1 = 0.5 x 6 = 3 V
