Question

6 j work is done in moving a positive charge of 3 C between two points . find the p.d between the points.​

Answer 1

ANSWER:

Potential difference between the points is 2 volt

GIVEN:

Work done = 6 joule

Charge = 3 coloumb

TO FIND:

Potential difference between the points.

SOLUTION:

Formula

$potential \: difference (v) = \frac{work \: done(w)}{charge(q)}$

Putting:

W = 6j

Q = 3c

$\implies \: v = \frac{6}{3} \\ \implies \: v = 2$

so, potential difference between the points is 2 volt.

NOTE:

some important formulas

$\implies \: v = \frac{w}{q} \\ \implies \: i = \frac{q}{t} \\ \implies \: v = i \times r \\ \implies \: p = \: v \times i \\ \implies \: h = i {}^{2} rt$

Where v= potential difference. w= work done

q = charge. t = time

r = resistance.
