To calculate the current in the parallel circuit we need the concept of ohms law,
V=IR
we know the resistance, R=48 ohms
voltage will be constant as 220-230 volts
so, I= V/R = 230/48 = 4.791 A
Add currents of three lamps, ie., I = 14.375
In a series circuit, current has to pass through each part of the circuit. In a parallel circuit, the current has several alternative paths.
A circuit that has more than one path for the current to flow is a parallel circuit. The circuit must have two or more paths to be considered parallel. A circuit that has only one current path through multiple components is a series circuit.
Parallel circuit
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
True...!
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.
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, 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.
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).
True
• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
In a parallel circuit, each branch has its own current flow, so there isn't a single device that has the smallest current. The current through each device is determined by its resistance and voltage applied. The device with the highest resistance will have the smallest current flowing through it in a parallel circuit.
