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.

How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What is the significance of using inductor in ac circuit?
Current filtering
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
How a multimeter be connected in order to measure resistance?
A: A multimeter is an instrument design to measure ohms volts and amps. So to measure amps a shunt is provided to allow a sample of the current to be measured as a function of voltage.
What is the difference between DC and AC?
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
How can you identify the branch parallel circuit with the what will have the least amount of current flow?
In a DC circuit, it's the branch with the largest resistance. In an AC circuit, it's the branch with the largest magnitude of impedance.
Why should current be reversed in an AC circuit?
The current in any AC circuit reverses every cycle.
Is a switch in series with what it controls or in parallel?
A switch is typically placed in series with what it controls to interrupt the flow of current when the switch is off. Placing it in parallel would keep the circuit closed even when the switch is off.
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
Can electricity flow through a parallel circuit?
Yes, electricity can flow through a parallel circuit. In a parallel circuit, the components are connected across the same voltage source, allowing multiple paths for the current to flow simultaneously. This results in different branches receiving the same voltage, but with different currents flowing through them.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
In a capacitive AC circuit the current is?
leading the voltage.
What statement descibes the flow of electic current in an AC circuit?
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
If an electric current is flowing through a parallel circuit which units tell you about the amount of electrons traveling in the circuit?
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
In an ac circuit?
current flows back and forth APEX
What is the significance of using inductor in ac circuit?
