**Reactive Load**. **In resistive load** - An increase in load means a decrease in resistance, causes an increase in current and power. Resistive load has a PF of 1 or unity. A Reactive load also known as the Capacitive or Inductive. These introduces an opposition to the Power that is uses to drive it.

Power Triangle is **a right angled triangle whose sides represent the active, reactive and apparent power**. Base, Perpendicular and Hypogenous of this right angled triangle denotes the Active, Reactive and Apparent power respectively.

Step response of Driver series RL circuit:-**At t=0 ^{-}, switch k is about to close but not fully closed**. As voltage is not applied to the circuit, current in the circuit will be zero. In this current through inductor can not change instantaneously. Let initial current through inductor can be represented as I

**The combination of a resistor and capacitor connected in series to an AC source** is called a series RC circuit. Figure 1 shows a resistor and pure or ideal capacitor connected in series with an AC voltage source. The current flow in the circuit causes voltage drops to be produced across the capacitor and the resistor.

A **resistor–inductor circuit** (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source.

An RL circuit acts as a **high pass** filter when constructed as shown in Figure 3. In the circuit shown, the resistor is the series component and the inductor is the shunt component.

SOURCE-FREE RL CIRCUIT

• **A circuit with series connection**. **of a resistor and inductor**. • Current i(t) through the inductor is considered as response of this system. At t = 0, assume that the inductor has an initial.

**Reactive Load**. **In resistive load** - An increase in load means a decrease in resistance, causes an increase in current and power. Resistive load has a PF of 1 or unity. A Reactive load also known as the Capacitive or Inductive. These introduces an opposition to the Power that is uses to drive it.

**Capacitors are connected together in parallel when both of its terminals are connected to each terminal of another capacitor**. The voltage ( Vc ) connected across all the capacitors that are connected in parallel is THE SAME.

**henry, unit of either self-inductance or mutual inductance**, abbreviated H, and named for the American physicist Joseph Henry. One henry is the value of self-inductance in a closed circuit or coil in which one volt is produced by a variation of the inducing current of one ampere per second.

A LR circuit consists of an inductor and a resistor in it. Where the inductor is denoted by L an the resistance is denoted by R . This type of combined circuit is applicable for AC currents and the combined effect of these two values is known as impedance and denoted by “Z” and the value for LR circuit is **√(R ^{2} +ω^{2} L^{2})**.

characteristic time constant: denoted by τ, of a particular series RL circuit is calculated by **τ=LR** τ = L R , where L is the inductance and R is the resistance.

**Series RL Circuit Analysis**

- Since the value of frequency and inductor are known, so firstly calculate the value of inductive reactance X
_{L}: X_{L}= 2πfL ohms. - From the value of X
_{L}and R, calculate the total impedance of the circuit which is given by. - Calculate the total phase angle for the circuit θ = tan
^{–}^{1}(X_{L}/ R).

RL Circuit Uses

Used as **high pass filter or low pass filter**. **Used in chokes of tube lights**. **Used in the filtering of low power signals and stores energy in the form of potential magnetic energy**.

To find the cutoff frequency for a high pass RL filter, proceed as follows: **Multiply the inductance value ( L ) with 2π .** **Divide the resistance ( R ) by the value from step 1**. You have determined the cutoff frequency of the high pass RL filter.

Kirchhoffs Voltage Law or KVL, states that “**in any closed loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop**” which is also equal to zero. In other words the algebraic sum of all voltages within the loop must be equal to zero.

The main components, or elements, of math are: **addition, subtraction, multiplication and division**.

Work and Power Difference in Tabular Form

Measurement Unit (SI unit) | The standard unit of work is the Joule denoted as (J). Furthermore, you can measure work in electron volt (eV), kWh, GWh, and MWh |

**Because of that, many types of logs exist, including:**

- Event logs.
- Server logs.
- System logs.
- Authorization logs and access logs.
- Change logs.
- Availability logs.
- Resource logs.
- Threat logs.

When budgeting, businesses of all kinds typically focus on three types of capital: **working capital, equity capital, and debt capital**.

A complex circuit configuration is **one that contains components that neither a parallel nor series with each other**. If a circuit can be reduced to a single resistor, it is a series or parallel. If not, it is a complex circuit.
