Question

Calculate the impedance of a condenser in order to run a bulb rated at 10 watt 60 volt when connected in series to an AC source of 100 volt.
I want solution also plzz help​

Answer 1

Answer:

The impedance of a condenser is 360 Ω.

Explanation:

Given that,

Power of the bulb = 10 watt

Operating voltage = 60 V

We need to calculate the impedance of a condenser

Using formula of impedance

$Z=\dfrac{v^2}{P}$

Where, V = operating voltage

P = power

Put the value into the formula

$Z=\dfrac{60^2}{10}$

$Z=\dfrac{3600}{10}$

$Z=360\ \Omega$

Hence, The impedance of a condenser is 360 Ω.

Answer 2

Explanation:

current will same in both condenser and bulb

voltage across bulb is given

we find current
