Question

write formula of chapter electricity​

Answer 1

Explanation:The formulas used in class X are-

1- I,current=Q,charge/T,time

2- V,potential differnce=W,work done/Q,charge

3-V,potential difference=I,current*R,resistance

4-Resisitivity=(R,resistance*A,area)/L,length

5-H,heat=I2Rt

6-P,power=VI=I2r=V2/r

Some more important formulas-

1-F,force=Q,charge*E,electric field intensity

2-V=(K,constant of proportionality of columb's law*Q)/R,distance or radius

3-E=(KQ)/R2

4-F=KQ1Q2/R2

{{Columb's law}}

Note:- K=9*109 N/m

Answer 2

Hey Ma8,


***

I = Q / T

V = W / Q

V = R × I

R = RESISTIVITY × LENGTH / AREA

RESISTIVITY = RESISTANCE × AREA / LENGTH

H = ${i}^{2} \times r\times t$

P = W / T

P = I × V

$p = {i}^{2} + \times r$

P = ${v}^{2} \div r$

RESISTOR IN SERIES => R1 + R2 + R3

RESISTOR IN PARALLEL = >

$\frac{1}{r} = \frac{1}{r1} + \frac{1}{r2}$
