D.C. Circuits Parallel Voltage

Hereโ€™s an โ€œingeliousโ€ way to understand why the voltages across resistors in JC A Level H2 Physics D.C. Circuits are the same.

Since the unit of voltages is J/C, you can visualise each charge to carry 1J of energy. As each charge moves into the respective branches, they carry their 1J energies along with them. Therefore, they have a voltage of 1V.

For series circuit, since all the charges are moving through the same set of resistors, they will all experience the same amount of potential drop as they passes through the resistors.
