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.
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.
For each individual branch, you can use Ohm's Law - just divide the voltage by the resistance.
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.
parallel
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.
sum the individual branch currents
They are not. They are connected differently, and the voltages and currents behave in different ways.
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
True...!
With the possible exception of some circuits that have inductance and capacitance in parallel and are excited by a pulse or an alternating voltage, the currents in two parallel branches of a circuit are ALWAYS in the same direction.
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).
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.
A parallel circuit has different paths for current to flow. In a parallel circuit, the components are connected side by side, allowing current to flow through multiple paths simultaneously. This results in different currents flowing through each path based on the resistance of the components.
In a parallel circuit, each branch has its own current path, allowing the total current to be the sum of the currents in each branch. This is why it is known as current magnification. However, at resonance, the impedance in the circuit is at its minimum, causing the total current in the circuit to decrease. This does not change the fact that individual branches can still have higher currents than in a series circuit due to the unique current paths in a parallel arrangement.
In the circuit shown, there are potentially three different currents.
In a parallel circuit, each component has its own separate path for current to flow from the power source. This means that if one component fails, the others can continue to operate independently. The total current flowing into the circuit is equal to the sum of the currents flowing through each individual component.
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
