Draw an electric circuit with a cell, key, ammeter, a resistor (series) of 2 ohm with combination of two resistors (4 ohm each) in parallel and a voltmeter across parallel combination.

As per the question, Will the potential difference across the 2 Ω resistor be similar to the one across the parallel combination with 4Ω resistors? The following reasons can be illustrated:

Step 1: Circuit Diagram

The circuit diagram with a cell, key, ammeter, resistors in series (2 $\Omega$) with a combination of two resistors can be represented as:

Electric Circuit Diagram

Step 2: Solution

Effective resistance of the parallel connected combination of two resistors is:

R_eff = ${4\ \times\ 4} \over {4\ +\ 4}$

⇒ R_eff = ${{16} \over 8}$

⇒ R_eff = 2Ω

Hence, because of the 2 Ω resistor and the parallel combination of two 4 Ω resistors are connected in series, the flow of current will be in the same direction. Due to this reason, the potential difference that occurs between the two-ohm resistors is similar to the potential difference between two resistors jointly.

Capacitors are manufactured with certain standard capacitances and working voltages. However, these standard values may not be the ones that are actually needed in a particular application. Two or more capacitors can be grouped in series or in parallel to achieve desired capacitance and voltage. When connected in series, the total capacitance decreases while the voltage rating increases, whereas in parallel connections, the total capacitance increases and maintains the same voltage rating. A capacitor stores energy in the electric field between its plates and stored energy is proportional to the square of the voltage and capacitance $U = \frac{1}{2}CV^2$, where symbols have their usual meanings.
Two capacitors, one of $3 \ \mu$F and the other of $6 \ \mu$F, are connected in series in the circuit as shown in the figure, for a long time. }
