(a) The circuit for the battery and resistance is shown in figure.

(b) Effective resistance of the series combinations is given as:

R=20+20=40ohms

(c) Current flowing through the circuit 

I=RV

=5/40=0.125amps

(d) p.d. across each resistance 

V=I×R=0.125×20=2.5V

Given,

voltage V = 5V

resistance R = 5 ohm

Current I = to find

we know that,

$V = IR \: \\ \implies \: I = \frac{V}{R} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{5}{5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1 \: A$
