Parallel circuit.
A parallel circuit. Since a parallel circuit has only two nodes, there can be only one voltage difference between the nodes.
The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb. Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.
The voltage between the ends of the circuit doesn't change ... that's where the power source is connected. But when you add more items in a series circuit, the voltage across each item changes. The individual voltages across each item in the series circuit always add up to the voltage of the power source. So in general, if you add more items, the voltage across each of the original ones must drop somewhat.
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
Voltage will be same in all branches. Voltage= Current * Total Resistance

The voltage is the same across all branches.
A parallel circuit. Since a parallel circuit has only two nodes, there can be only one voltage difference between the nodes.
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
In a parallel circuit the voltage across each component is the same.

The same voltage is present but does not run. It is the current that could be described as "runniing" through the different branches. Just by definition, parallel circuits necessarily have the same voltage. It is architecture of the circuit.
the same In a parallel circuit, the voltage travels through all the closed circuit paths. They are not branches.
In all branches of a parallel circuit, it is voltage that is the same. Across each parallel branch of a circuit, we'll measure the same voltage. Probably the best example of equal voltages appearing across all branches of a parallel circuit is a household electrical distribution curcuit. The voltage at any outlet where you'd care to plug in an appliance or device will be the same. A fan plugged into an outlet in a bedroom will "feel" the same voltage as it would if it were in the living room and plugged into an outlet there.One other way to look at things like this is that each branch of the parallel circuit is connected across the voltage source. Each branch could be looked at as an "independent" circuit, and any given branch doesn't care what is happening in any other branch. Does turning that fan we mentioned on and off, or even unplugging it from the outlet affect the operation of, say, the refrigerator? No, it does not. Any device plugged into an outlet is connected "directly" to the source of voltage. And each parallel branch of the circuit will operate independently of any other branch. We know that the voltage in (or across) any branch of a parallel circuit is the same as the voltage across any other branch.
No. The current in a series circuit is the same everywhere. The voltage across a parallel circuit is the same.
voltage is devided only in series circuit and is the same at the parallel circuit
