Step 1
The expression for equivalent resistance of the resistor connected in series is,

R e q = R_{1} + R_{2} + R_{3}

= 2 Ω + 3 Ω + 4 Ω

= 9 Ω

Step 2
For parallel connection

\frac{1}{R e q} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}}

\Rightarrow R e q = \frac{R_{1} R_{2}}{R_{1} + R_{2}} = \frac{6 Ω \times 3 Ω}{6 Ω + 3 Ω}

\Rightarrow R e q = \frac{9 Ω \times 2 Ω}{9 Ω}

\Rightarrow R e q = 2 Ω

Step 1
Solution:
1) Equivalent resistance

= 2 + 3 + 4 = 9 o h m

2) Equivalent resistance

= \frac{6 \times 3}{6 + 3} = \frac{18}{9} = 2 o h m
