Answer 1

1st one is series combination of resistors

and 2nd is parallel combination of resistors

Answer 2

Answer:

The circuit diagram of parallel and series combination for 3 resistor are

Explanation:

• Parallel combnation

Three Resistors with resistance $R_{1}, R_{2}, R_{3}$connected between the points $C$ and $D$.

• The ammeter monitors the current in a specific branch, whereas the voltmeter measures the potential difference V between Cand D and the ammeter.

Let $I$ be the total current passing through the circuit. $I_{1}, I_{2}$ and $I_{3}$ be the current passing through the resistor of resistance $\mathrm{R}_{1}, \mathrm{R}_{2}$ and $\mathrm{R}_{3}$respectively.

$\mathrm{I}=\mathrm{I}_{1}+\mathrm{I}_{2}+\mathrm{I}_{3}$

• series combination

Here $\mathrm{R}_{1}, \mathrm{R}_{2}$ and $\mathrm{R}_{3}$  are the three resistors.

$I =$electric current

$\mathrm{V}=$ the potential difference

Applying the Ohm's law

$\mathrm{V}=\mathrm{IR}$

On applying Ohm's law to the three resistors separately, we further have

$\mathrm{V}_{1}=\mathrm{IR}_{1}$

$\mathrm{V}_{2}=\mathrm{IR}_{2}$

and $\mathrm{V}_{3}=\mathrm{IR}_{3}$

• The total potential difference across a series of resistors is equal to the sum of the individual resistors' potential differences.

$\mathrm{V}=\mathrm{V}_{1}+\mathrm{V}_{2}+\mathrm{V}_{3}$
