To determine the current flow in the wire, first find the
inductive reactance of
the coil. The inductive reactance equals 6.28 times 60 hertz times 0.3 henries which equals 113.1 ohms. Now use Ohm’s Law and divide 120 volts by 113.1 ohms which equals 1.06 amps.
What is coil current?
A current coil is basically a coil, such as,
a wire wrapped around an electrical conductor
How do I calculate current?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as
I = V/R
. The SI unit of current is Ampere (Amp).
How do you find the current of an inductor?
The current, i that flows through an inductor produces
a magnetic flux that is proportional to it
. But unlike a Capacitor which oppose a change of voltage across their plates, an inductor opposes the rate of change of current flowing through it due to the build up of self-induced energy within its magnetic field.
How do you find the current in a loop?
A current traveling through a loop of wire creates a magnetic field along the axis of the loop. The direction of the field inside the loop can be found by
curling the fingers of the right hand in the direction of the current through the loop
; the thumb then points in the direction of the magnetic field.
Is current the same in parallel?
A Parallel circuit has certain characteristics and basic rules: …
Voltage is the same across each component of the parallel circuit
. The sum of the currents through each path is equal to the total current that flows from the source.
What is the power factor formula?
It is found by
multiplying (kVA = V x A)
. The result is expressed as kVA units. PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit.
What is inductor formula?
The inductor equation tells us:
v = L d i d t v = text L,dfrac{di}{dt} v=Ldtdi
. This says the voltage across an inductor is proportional to the rate of change of the current through the inductor. Since the current source provides a constant current, the rate of change, or slope, of the current is 0.
Does current flow through an inductor?
The current, i that flows through an inductor produces a magnetic flux that
is proportional to it
. But unlike a Capacitor which oppose a change of voltage across their plates, an inductor opposes the rate of change of current flowing through it due to the build up of self-induced energy within its magnetic field.
What are the types of inductor?
- Air-core Inductor. The commonly seen inductor, with a simple winding is this air-Core Inductor. …
- Iron-Core Inductor. These Inductors have Ferromagnetic materials, such as ferrite or iron, as the core material. …
- Toroidal Inductors. …
- Laminated Core Inductors. …
- Powdered Iron Core Inductors.
What is the loop rule?
Kirchhoff’s loop rule states that the algebraic sum of potential differences, including voltage supplied by the voltage sources and resistive elements, in
any loop must be equal to zero
.
How does Loop area affect the current flow?
The loop area effects the flow of current. So,
if we decrease the loop area will are increasing the flow of current
, while increasing the loop area will decrease the flow of current. . … As the bar magnet enters the coil from the left, draw (see example) a Right-Hand-Rule to describe the conventional current flow.
How does the loop rule work?
Answer: Kirchhoff’s Loop Rule states that
the sum of the voltage differences around the loop must be equal to zero
. To find the sum, a direction of travel must be chosen. The direction of positive current is given as clockwise, and so it is easiest to use this as the direction of travel to find the sum.
Why the current is not same in parallel circuit?
The
total current in the circuit must remain constant
(so that charge is not created/lost). So the sum of the currents in the parallel branches will always be equal to the current before the junction. If the resistance in one branch is decreased the current will increase along that branch.
Why current is divided in parallel?
When resistors are connected in parallel,
more current flows from the source than would flow for any of them individually
, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.
How does current behave in a parallel circuit?
The current in a parallel circuit
splits into different branches then combines again before it goes back into the supply
. When the current splits, the current in each branch after the split adds up to the same as the current just before the split.
