Question

how changing the number of components in a circuit affects the outcome with reference to the given circuit.

Answer 1

Answer:

Explanation:

Let's consider ,the components that affect electrical circuit ,as inductor , capacitor , and resistor.

DC circuit, connect inductor to dc source,it gets magnetised ,some voltage drop will be there and heat also produced,so inductor cause some loss,as it has resistance.

DC circuit, connect capacitor to dc source , capacitor gets charged until charge potential equals to applied voltage, so it doesn't consume any power but blocks the current flow,when fully charged.

DC circuit connect resistor ,it resist the flow of current causes voltage drop as well generate heat.

AC circuit same thing will happen but ,inductor causes current to lag behind voltage ,power factor reduces and heat produced too.

AC circuit being sinusoidal in nature capacitor ,charge /discharge, causes current to lead voltage it does not consume any power hence power factor tends to increase.

AC circuit connect resistor it causes voltage drop as well heat generates and power loss

Answer 2

Answer:

According to Ohm’s law

V = IR

where

V= potential difference

I= Current

R = Resistance

We can also modify the above equation as

I = V/R ——- (1)

Now given that the potential difference across the two ends of the component decreases to half

Let the new potential difference be

Vʹ= V/2———(2)

Resistance remains constant across the electrical component

So the new current is drawn through the electrical component is

Iʹ = Vʹ/R———–(3)

Substitute the value of V’ from equation (2) in equation (3), we get

I’ = (V/2)/R

I’ = (1/2) (V/R)

Since V/R = I

I’ = (1/2) I

I’ = I/2

Therefore, the amount of current flowing through the electrical component is reduced by half.
