Which type of energy is stored in a capacitor? electric potential energy chemical energy gravitational energy heat energy

1 answer:

6 0

Energy stored in a capacitor is Electric Potential Energy. Capacitor is device used for storing energy. The work done to charge is a capacitor is stored in it in the form of Electrical potential energy. Electrical potential energy is defined as capacity to do work due to the position change. For example, we know fans have capacitor installed in it. When we turn off the fan, it continue moving using the electrical energy stored in the capacitor.

The 400-turn primary coil of a step-down transformer is connected to an ac line that is 120 V rms. The secondary coil voltage is

KengaRu [80]

Explanation:

The given data is as follows.

$V_{1}$ = 120 V, $V_{2}$ = 6.50 V

$N_{1}$ = 400, $N_{2}$ = ?

Formula to calculate the number of turns in secondary coil are as follows.

$\frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}$

Putting the given values into the above formula as follows.

$\frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}$

$\frac{400}{N_{2}} = \frac{120}{6.50}$

$N_{2}$ = 21.66

= 22 (approx)

Thus, we can conclude that number of turns in the secondary coil are 22.

Lady bird [3.3K]

It was thought that no one had studied further in the works of JJ Thomson and John Dalton at their time because there was no sufficient technology to conduct their works. However, their theory was eventually revised when Neils Bohr had theorised the modern atomic structure we know today.
