volts in parallel circuit

All points connected by a conductor are at the same potential.

Tes is right as usual Umer but I wonder if we might have misunderstood your q

Voltage is equivalent to height. (Voltage is a measure of 'potential difference' which equates to difference in potential energy). All routes down from the top A of a hill to a particular end location B will involve the same drop of height no matter how which route is taken. Parallel circuits involve different routes starting from a common junction A and ending at another common junction B. The voltage drop between A and B is constant no matter which route is taken

Um they don't, exactly. Wherever there's resistance, however slight, there will be a voltage drop

...unless there's no load. So some of us are still a bit uncertain about your q

Voltage is the energy per free electron whereas current is the rate of flow of free electrons across the conductor's cross-sectional area.
