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.

How do parallel circuits use current and voltage?
Kirchoff's voltage law: In a series circuit, the signed sum of the voltage drops around the circuit add up to zero. Since a parallel circuit (just the two components of the parallel circuit) also represents a series circuit, this means that the voltage across two elements in parallel must be the same.Kirchoff's current law: The signed sum of the currents entering a node is zero. In a series circuit, this means that the current at every point in that circuit is equal. In a parallel circuit, the currents entering that portion of the circuit divide, but the sum of those divided currents is equal to the current supplying them.
In a parallel circuit does the power of each branch add up?
Yes, the total power dissipated through the circuit is equal to the sum of the power of each branch in a parallel circuit.
How do you find the branch current in parallel circuit?
For each individual branch, you can use Ohm's Law - just divide the voltage by the resistance.
Why is there no effect on other branches in a parallel circuit when one branch of the circuit is opened or closed?
this is because the energy can still flow through the other branches.
What is the relationship between the current leaving the source and the current through each load in a parallel circuit?
You should study up on Kirchov's Current Law (KCL). It is the means of answering your question and a tool for understanding all parallel circuit configurations.AnswerKirchhoff's current law will tell you that the supply current is equal to the sum of the branch currents.
When two resistors are conected in parallel what happens to the current as it passes through the circuit?
According to Kirchhoff's Current Law, the sum of the individual branch currents must be equal to the total current before (and after) it branches.
Is the current in one branch of a parallel circuit more than less than or equal to the total current entering the junction point of the circuit?
Answer: less. Answer: Kirchhoff's Current Law states that the sum of all currents into a junction (or out of a junction) must be zero. This refers to the algebraic some, that is, if you consider the current into the junction, any current entering the junction will be counted as positive, while any current leaving the junction will be counted as negative. Thus, any individual current will be equal to the negative of the sum of all the other branches at the junction.
In a parallel circuit what is the total current equal to?
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.
How do resistance behave in parallel circuit?
in a parallel circuit resistance decreases increasing the current.
What is a circuit with more than one path to flow?
All the branch circuits in your house are parallel. They have a constant voltage applied to any device plugged into an outlet. If you thought about an analogy for a parallel circuit, imagine that the rails on each side of rungs represented the hot and neutral wires of a typical household branch circuit. The rungs would be the loads connected in parallel. Each "load" draws the current needed to operate the specific device. The sum of all the currents for the "loads" is equal to the total current being supplied through the circuit.
