Resistance, Inductance and Capacitor

In summary, Resistance is a property of a material or component that impedes the flow of electrical current and is measured in ohms. Inductance is a property of a conductor or circuit that causes a voltage to be induced in response to a changing current and is measured in henrys. Capacitance is a property of a conductor or circuit that allows it to store electrical charge and is measured in farads. These three properties are related through the concept of impedance, which is the overall opposition to current flow in a circuit and is denoted by the symbol "Z". They can be measured using specialized tools such as ohmmeters, inductance meters, and capacitance meters.

Can some check my answer, please? I only did number 1 because I have no idea how to do number 2.


NOTE: Calculators are not allowed, so no need to give the exact value. For example, if the answer has √2, just leave it as √2, instead of writing it as 1.41...

Power source voltage e(t) = √2*20sin2t [V],
current i(t) = 5sin(2t - ∏/4) [A].

1. Find the values of resistance R, and inductance L.
2. Let V be the phasor of voltage v(t). Find the capacitance value of the capacitor C that maximizes the magnitude of V.

Related to Resistance, Inductance and Capacitor

What is resistance?

Resistance is a property of a material or component that impedes the flow of electrical current. It is measured in ohms and is denoted by the symbol "R". The higher the resistance, the more difficult it is for current to flow through the material or component.

What is inductance?

Inductance is a property of a conductor or circuit that causes a voltage to be induced in response to a changing current. It is measured in henrys and is denoted by the symbol "L". Inductance is also known as "self-inductance" when it is present in a single conductor, and "mutual inductance" when it is present in a circuit with multiple conductors.

What is capacitance?

Capacitance is a property of a conductor or circuit that allows it to store electrical charge. It is measured in farads and is denoted by the symbol "C". Capacitors are the most common components used to introduce capacitance into a circuit. They consist of two conductive plates separated by an insulating material, and can store energy in the form of an electric field.

How are resistance, inductance, and capacitance related?

Resistance, inductance, and capacitance are related through the concept of impedance, which is the overall opposition to current flow in a circuit. Impedance is a combination of resistance, inductance, and capacitance, and is denoted by the symbol "Z". In a series circuit, the impedance is the sum of the individual values for resistance, inductance, and capacitance. In a parallel circuit, the impedance is the reciprocal of the sum of the individual reciprocals for resistance, inductance, and capacitance.

How are resistance, inductance, and capacitance measured?

Resistance is typically measured using an ohmmeter, which applies a known voltage to a circuit and measures the resulting current. Inductance is often measured using an inductance meter, which applies a known AC voltage to a circuit and measures the resulting current and phase shift. Capacitance is typically measured using a capacitance meter, which applies a known AC voltage to a circuit and measures the resulting current and phase shift.
