A dielectric material, such as Teflon , is placed between the plates of a parallel-plate capacitor without altering the structur

e of the capacitor. The charge on the capacitor is held fixed. How is the voltage across the plates of the capacitor affected? 1. The voltage decreases because of the insertion of the Teflon . 2. The voltage becomes infinite because of the insertion of the Teflon . 3. The voltage increases because of the insertion of the Teflon . 4. The voltage becomes zero after the insertion of the Teflon . 5. The voltage is not altered, because the structure remains unchanged.

Answer:

1. The voltage decreases because of the insertion of the Teflon.

Explanation:

When we placed the dielectric medium/material between the plates of the capacitor. It increases the capacitance. Increase in capacitance means that the electric field between the plates will decrease and thus there will be a decrease in voltage. As we know that the capacitance has an inverse relation with the electric field between the plates. Mathematically,

q = CV\\C = Q/V

where C is capacitance, V is Voltage and q is a charge.

By putting "Teflon between the plates of capacitor there will be a decrease in voltage."

\Large {{ \sf {Question :}}}

<h3>A boy who is riding his bicycle, moves with an initial velocity of 5 m/s. Ten second later, he is moving at 15 m/s. What is his acceleration?</h3>

\Large {{ \sf {Given :}}}

<h3>Initial Velocity (<em>u</em>) - 5 m/s</h3><h3>Final Velocity (<em>v</em>) - 15 m/s</h3><h3>Time (<em>t</em>) - 10 sec</h3>

\Large {{ \sf {Formulae  :}}}

<h3>If the velocity of an object changes from an initial value <em>u </em>to the final value <em>v </em>in time <em>t,</em><em> </em>the acceleration <em>a</em> is, </h3><h3>a \:  =  \frac{v - u}{t}</h3><h3>\Large {{ \sf {Step-by-step explanation :}}}</h3>

a \:  =  \frac{v - u}{t}  \\ or \:  \: a =  \frac{(15 - 5)}{10} m \: s^{ - 2}  \\ or \:  \: a \:  =  \frac{10}{10}m \: s^{ - 2} \\ or \:  \: a = 1m \: s^{ - 2}
