Answer 1

$\large{\underline{\sf{\red{Answer:}}}}$

$\large{\underbrace{\sf{\purple{Resistance:}}}}$

• Resistance is a measured of the opposition to current flow in an electrical circuit.
• It is measured in ohms, symbolized by the Greek letter omega (Ω).
• All materials resist current flow to some degree.
• Ohms are named after a German physicist Georg Simon. He studied the relationship between voltage, current and resistance.

Formula:-

→ $\rm{R=\dfrac{V}{I} }$

• R = resistance (Ohms, Ω)
• V = voltage difference which is between the two ends of a resistor (Volts, V)
• I = the current which flows through a resistor (Amperes, A)

$\large{\underbrace{\sf{\purple{Reactance:}}}}$

• In electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element's inductance or capacitance.
• Reactance is similar to electric resistance in this respect, but differs in that reactance does not lead to dissipation of electrical energy as heat.

Types of Reactance:-

• Capacitive reactance (Ohms is the unit)
• Inductive reactance (Ohms is the unit)

Formula:-

→ $\rm{X_c=\dfrac{1}{2 \pi f C}  }$

• XC = capacitive reactance
• f = frequency
• C = capacitance

$\large{\underbrace{\sf{\purple{Impedance:}}}}$

• Impedance is the total opposition to alternating current by an electric circuit, it is equal to the square root of the sum of the squares of the resistance and reactance of the circuit and usually expressed in ohms.
• Impedance is denoted as Z.

Formula:-

→ $\rm{Z=\sqrt{R^{2} +(X_L-X_C)^{2} }  }$

• Z = impedance
• R =  resistance
• $\rm X_L$ = inductive reactance
• $\rm X_C$ = capacitive reactance

Answer 2

Answer:

Resistance:

• Resistance is a measured of the opposition to current flow in an electrical circuit.
• It is measured in ohms, symbolized by the Greek letter omega (Ω).
• All materials resist current flow to some degree.
• Ohms are named after a German physicist Georg Simon. He studied the relationship between voltage, current and resistance.

Formula:-

→ R=V/I

R = resistance (Ohms, Ω)

V = voltage difference which is between the two ends of a resistor (Volts, V)

I = the current which flows through a resistor (Amperes, A)

Reactance:

• In electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element's inductance or capacitance.
• Reactance is similar to electric resistance in this respect, but differs in that reactance does not lead to dissipation of electrical energy as heat.

Types of Reactance:-

Capacitive reactance (Ohms is the unit)

Inductive reactance (Ohms is the unit)

Formula:-

=> Xc = 2πfC1

XC = capacitive reactance

f = frequency

C = capacitance

Impedance:

• Impedance is the total opposition to alternating current by an electric circuit, it is equal to the square root of the sum of the squares of the resistance and reactance of the circuit and usually expressed in ohms.
• Impedance is denoted as Z.

Formula:-

→ \rm{Z=\sqrt{R^{2} +(X_L-X_C)^{2} } }Z=

R2

+(XL−XC)2

Z = impedance

R = resistance

\rm X_LXL

= inductive reactance

\rm X_CX lC

= capacitive reactance
