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.

4 How do you determine current in a parallel DC circuit?
The current in each individual component of the parallel circuit is equal to (voltage across the combined group of parallel components) / (individual component's resistance). The total current is the sum of the individual currents. ============================== Another approach is to first calculate the combined effective resistance of the group of parallel components. -- take the reciprocal of each individual resistance -- add all the reciprocals -- the combined effective resistance is the reciprocal of the sum. Then, the total current through the parallel circuit is (voltage across the parallel circuit) / (combined effective resistance of the components).
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
What happens as a current flows through a parallel circuit?
if the circuit is a series circuit (all loads wired in a single line , one after the other ) then the current will be the same in any part of the circuit . if there are several different paths for the current to take , then each path will carry a different percentage of the total current . when each of these different current values are added together , they will equal the total supplied current.
Does the total current of a parallel RLC circuit is equal to the sum of current in resistor inductor and capacitor?
the total current is the vector sum of current expressed in this equation: IT = sqrt ((V/R^2) + (V/XC-V/XL)^2)) since the voltage(V) is equal in every branch due to parallel. we can substiture the value of V to our equation. V = supply voltage (possible).
What is the total resistance in a parrellel ciruit?
The rule for finding total resistance in a parallel circuit is that a parallel circuit has two or more paths for current to flow through. Another rule states that voltage is the same across each component of the parallel circuit. If one of the parallel paths is broken, current will still continue to flow in all the other paths.
Is the current in one branch of a parallel circuit more than less than or equal to the total current?
its less then the total current
what happens to current in a circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
In a parallel circuit with two branches the voltage is equal across both branches and the current?
In a parallel circuit with two branches, the voltage is the same across each branch and the current is divided between the branches. The total current entering the parallel circuit is equal to the sum of the currents in each branch.

What is a circuit with several current paths whose total current equals the sum of the currents in its branches?
This is a parallel circuit, each of the parallel current paths draws a certain current, and the input current equals the output current, so the sum of all current through each path has to equal the total current.
What is a circuit with several current paths whose total current equals the sum of the currents in its branches called?
This is a parallel circuit, each of the parallel current paths draws a certain current, and the input current equals the output current, so the sum of all current through each path has to equal the total current.
What is the hypothesis for parallel circuits?
In a parallel circuit, the hypothesis is that when components are connected in parallel, the total current flowing into the junction equals the total current flowing out. Essentially, the hypothesis states that the total current remains constant regardless of the number of parallel paths.
What is the three laws of parallel circuit?
The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!

What happens to the current in a parallel circuit when more bulbs are added?
When more bulbs are added to a parallel circuit, the total current in the circuit increases because each bulb provides an additional path for current to flow. This is because in a parallel circuit, the current is divided amongst the branches, so adding more branches (bulbs) will increase the total current.
What is the current called when it flows from and back to the power supply in a parallel circuit?
The current that flows from and back to the power supply in a parallel circuit is called branch current. Each branch in a parallel circuit has its own current flow that combines to form the total current drawn from the power supply.
