cbse class 10 electricity all formulas​

Answer 1

Answer:

1. Current I I = Q / t Q = Charge t = time taken Amperes (A)

2. Voltage V V = E / Q or V = W / Q E = Energy, W = Work done Volts (V)

3. Resistance R R = ρl / A ρ = Resistivity, l = length, A = Area or, R = V / I Ohm (Ω)

4. Power P P = VI Watts (W)

Answer 2

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 or, R = V / I Ohm (Ω)

Power P P = VI Watts (W)

Conductivity σ sigma = 1 / ρ Siemens per meter (S/m)

Power =P =VI

conductivity =sigma=1/p
