Question

Please let me know all the formulas in science CBSE class ten

Answer 1

in physics,
electricity
V=W/Q potential difference
V=I*R ohms law
R=P*L/A P IS DENOTED AS ROW
SERIES AND parallel COMBINATION
power and heat formula

Answer 2

Light Reflection and Refraction

$m = \: \frac{{h}^{1} }{h}$

or

$m = - \frac{v}{u}$

mirror formula

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$

Lens formula

$\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$

Power of the lens

$p = \frac{1}{f(in \: m)} \: \: \: \: or \: \: \: \: \frac{100}{f \: (in \: cm)}$

Electricity

Electric Current

$I = \frac{Q}{t}$

Potential Difference

$V = \frac{W}{Q}$

OHMs Law

V=IR

Resistance

${R}=\frac {V}{I}$

Resistivity

$R = p \times \frac{L}{A}$

Heating

H = I²RT

or

H = VIt

Electrical energy

W= VIt = I²RT

Electrical Power

$P=\frac{W}{t}$
