Question

all formulas of electricity chapter

Answer 1

Electric Power Formulas
P = V I
P = R I2
P = V2/ R
where
P = power (Watts)
V =voltage(Volts)
I= current (Amperes)
R= resistance (Ohms)
Electric Current Formulas
I = V / RI = P / V
Electric Resistance Formulas
R = V / IR = V2/ P
R = P / I2
Electrical Potential Formulas - Ohms Law
Ohms law can be expressed as:V = R I
V/I=R.
I hope its helps u.

Answer 2

$\Large{\mathfrak{\underline{\underline{Answer :-}}}}$

Electricity Formulas :-

• I = Q / t

I = Current

Q = Charge

t = time taken

• V = E / Q
• V = W / Q

V = Voltage

E = Energy

W = Work done

• R = ρl / A

R = Resistance

ρ = Resistivity,

l = length

A = Area

• R = V / I

R = Resistance

• P = VI

P = Power

• sigma = 1 / ρ

Simga = Conductivity
