Which one of the following have the same value in all the ways round in series circuit.a.Chargeb.Currentc.Resistanced.Volte

The correct answer is b. Current.

Here's why:

In a series circuit, the current is the same at every point. This is because there is only one path for the current to flow. So, if you measure the current at different points in a series circuit, you will find that it is the same everywhere.

On the other hand, the voltage (or potential difference) across each component in a series circuit is not the same - it depends on the resistance of each component. The total voltage in the circuit is the sum of the voltages across each component.

The resistance in a series circuit is the sum of the individual resistances, so it also varies depending on the component.

The charge is not a property that is typically discussed in the context of a series circuit, but it's worth noting that the total charge flowing in the circuit is conserved.
