Do individual lines in a parallel circuit have different currents flowing through them?

They can.
The current in each "line" (correctly, *branch*) depends on (i) the applied voltage and (ii) the individual resistance in each branch.
If the branch resistances are different, the branch currents will be different.
Ohm's Law will let you calculate the individual currents.

What total current delivered to a number of devices connected in parallel is the sum of the individual currents in each device Circuit breakers are resettable automatic switches that protect against a?
Yes, the total current delivered to multiple devices in parallel is the sum of the individual branch currents (the vector sum if there is inductive load). Circuit breakers are resettable automatic switches that help protect against circuit overload (such as running too many hair driers and heaters on at one time) and faults (such as dropping the hair drier into a bathtub). Circuit breakers "operate" (or open) to stop current flow to the fault or overloaded 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.
Is the sum of the resistance in a parallel circuit always excessds the total resistance in a circuit?
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.
If the different parts of an electric circuit are found on separate branches of the circuit then what is that circuit called?
parallel
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.
How is a total current in a parallel circuit worked out?
sum the individual branch currents
How are parallel circuit and series circuit the same?
They are not. They are connected differently, and the voltages and currents behave in different ways.
Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
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).
What are the 3 laws of parallel circuit?
Components in a parallel circuit share the same voltage. Etotal = E1 = E2 = . . . EnTotal resistance in a parallel circuit is less than any of the individual resistances. Rtotal = 1 / (1/R1 + 1/R2 + . . . 1/Rn)Total current in a parallel circuit is equal to the sum of the individual branch currents. Itotal = I1 + I2+ . . . In Answered by MD.Nazeer Ahmed,MCET Student.
The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
Which circuit has different parts of the circuit on separate branches?
Any circuit that even has more than one branch is a parallel one.
How many parts can currents take in series and parallel circuits?
Series circuit: one path. Parallel circuit: One path for each branch (two or more).
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.
What do individual components in a parallel circuit experience the same of?
The voltage is the same across every individual component in a parallel configuration.
What is different between a series circuit and a parallel circuit?
In a parallel circuit there are multiple possible pathways for the current to flow.
