Circuits Question - Voltage and current in an inductor circuit

In summary, an inductor circuit is a type of electronic circuit that uses an inductor to store energy in the form of a magnetic field and control the flow of current. Voltage affects an inductor circuit by changing the magnetic field, resulting in a change in current. In an inductor circuit, voltage and current are directly proportional according to Ohm's law. Inductor circuits also create a lag in the flow of alternating current due to their opposition to changes in current. The main difference between an inductor and a resistor is their function, with a resistor limiting current flow and an inductor storing energy. The resistance of a resistor remains constant, while the inductance of an inductor varies with frequency.

The Attempt at a Solution



I found Zeq and there are exactly 2 Amps going into it. I'm not sure what to do from here.

[itex]Z_{eq} = \frac{<(arctan(\frac{R}{ωL}))}{ω^{2}L^{2}+R^{2}}[/itex]

I'm not sure what to do from here, thanks for any help.

Ok so because this is DC

ω = 2∏f

but f= 0

so

[itex]Z_{eq} = \frac{j}{R^{2}}[/itex]

Where do I go from here?

vL(t) = 120e-2500t

iL(t) = 2 + 6e-2500t

1. What is an inductor circuit?

An inductor circuit is a type of electronic circuit that contains an inductor, which is a passive electronic component that stores energy in the form of a magnetic field. Inductor circuits are commonly used in electronics to control and manipulate the flow of current.

2. How does voltage affect an inductor circuit?

Voltage affects an inductor circuit by creating a change in the magnetic field within the inductor. When the voltage is increased, the magnetic field expands, and when the voltage is decreased, the magnetic field collapses. This change in the magnetic field creates a current flow in the circuit.

3. What is the relationship between voltage and current in an inductor circuit?

In an inductor circuit, the voltage and current are directly proportional. This means that as the voltage increases, the current also increases, and as the voltage decreases, the current decreases. This relationship is known as Ohm's law and is expressed as V=IR, where V is voltage, I is current, and R is resistance.

4. How does an inductor circuit affect the flow of alternating current (AC)?

An inductor circuit affects the flow of alternating current by creating a lag in the current flow. This is because the inductor opposes changes in current flow, so it takes time for the current to build up in the circuit. As a result, the current in an inductor circuit lags behind the voltage by 90 degrees.

5. What is the difference between an inductor and a resistor in a circuit?

The main difference between an inductor and a resistor in a circuit is their function. A resistor is used to limit the flow of current in a circuit, while an inductor is used to store energy in the form of a magnetic field. Additionally, the resistance of a resistor remains constant, while the inductance of an inductor varies depending on the frequency of the current.
