Answer 1

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

Electricity Formulas :-

• I = Q / t

1. I = Current
2. Q = Charge
3. t = time taken

• V = E / Q
• V = W / Q

1. V = Voltage
2. E = Energy
3. W = Work done

• R = ρl / A

1. R = Resistance
2. ρ = Resistivity
3. l = length
4. A = Area

• R = V / I

1. R = Resistance

• P = VI

1. P = Power

• sigma = 1 / ρ

1. Simga = Conductivity

Answer 2

Quantity. formulas. unit

current l. l= q/t. amperes

q = charge. (A)

t= time taken

V= E /q

or

Volta ge. v= w/q. Volta (V)

V E= energy,

w = work done.

R = pl/ a

resistance. p= resistivity. ohm

r l= length

a= area

resistance. R= V/l ohm

R

power. p= vl. Watts

P. (w)

conductivity s.
