Is it true or wrong to say that components in series must have the same potential difference across them? Either yes or no explain it.

wrong

No. When resistors are connected in series, the potential difference across each is the same only if the resistors are the same. So, if you connect two 1,000 Ohm resistors in series; the potential difference across each will be the same.

I hope this helps.

No, it is not true to say that components in series must have the same potential difference across them.

When components are connected in series, they form a single path for the flow of current. In a series circuit, the total voltage supplied by the power source is divided among the components based on their individual resistance.

Each component in a series circuit has a voltage drop across it, which is determined by its resistance and the current flowing through the circuit. The voltage drop across each component is not necessarily the same. It depends on the resistance values of the components.

The sum of the voltage drops across all the components in a series circuit will always be equal to the total voltage of the power source, according to Kirchhoff's voltage law. However, the individual voltage drops across each component can be different.

To calculate the voltage drop across each component in a series circuit, you need to know the resistance of the component and the current flowing through the circuit. By using Ohm's Law, you can calculate the voltage drop across a component by multiplying its resistance by the current:

Voltage drop (V) = Resistance (R) * Current (I)

So, it is incorrect to claim that components in series always have the same potential difference across them. The potential difference across each component depends on its resistance and the current flowing through the circuit.
