Answer 1

$\huge\underline\mathfrak\red{Ello}$

$\huge\underline\mathfrak\red{</u></em></strong><strong><em><u>A</u></em></strong><strong><em><u>n</u></em></strong><strong><em><u>s</u></em></strong><strong><em><u>w</u></em></strong><strong><em><u>e</u></em></strong><strong><em><u>r</u></em></strong><strong><em><u>1</u></em></strong><strong><em><u>:-</u></em></strong><strong><em><u>}$

Protons interact in ways that electrons do not. ... Electrons are not affected by the strong force, and so they only get trapped by the electrical attraction to the nucleus which is much weaker in ionized atoms. Therefore it is easier for electrons to move away from one atom to another, transferring charge.

Material required :

battries of 1.5V, Conducting wires, iron spoke, LED bulb, ammeter, volt meter,

Procedure:

• Arrange the circuit as shown in the attachment.

• Connect the battery..and note the values of I and V in a table.

• Connect 2, 3, 4 and 5 battries and note the values of I and V in each case.

• Observe the temp. of spoke

• Next find the value of V/I in each case

• Now, remove the Iron spoke and connect the LED.

• Do the same..by connecting battries and note the values

• observe the temp. of LED

• Next find the value of V/I in each case.

• Draw the graphs..for the both iron spoke and LED cases and observe

Observation :

It will observed that the, V/I value is constant for IRON SPOKE..but, it isn't for lED

Also, the Temp. of Spoke is constant. But, the temp. of LED is not constant!

The graph of the values of I and V of spoke is linear..but, it is not linear for LED.

Result :

The constant valueofV/I..indicates that,the potential diff.is directly proportinal to Current!
