Answer:
(i) 0.1A. (ii) 1v
Explanation:
we know that, V=IR
therefore, current I=V/R
- resistance in series is given by Rs=R1+R2
=10+20.
=30
R=30Ω
and I=V/R
therefore I=3/30. =0.1A
the current flowing in the circuit is 0.1A
2. potential difference across 10 Ω resistor is
V=IR
V=0.1 x 10
V=1v
therefore potential difference across 10 Ω resistor is 1v
