Question

easy way to identify the electricity chapter class 10 numericals which formula we should use in which place please answer anyone I will mark it as bring this​

Answer 1

Current I

I = Q / t

Q = Charge

t = time taken

Amperes (A)

Voltage V V = E / Q

or

V = W / Q

E = Energy, W = Work done

Volts (V)

Resistance R  R = ρl / A

ρ = Resistivity,

l = length,

A = Area

Ohm (Ω)

Resistance R  R = V / I  ohm (Ω)

Power P  P = VI  Watts (W)
