Question

all formulas of electricity chapter

Answer 1

first unblock me
electric potential = Work/Charge

resistance = Potential difference / Current

1 ohm = 1 Volt / 1 Ampere

specific resistance = R * A / I

1 Hp = 746 Watt

Answer 2

V=IR

H=I^2Rt

V=W/Q

P=VI

P=V^2/R

Rp = R1+R2+R3

1/Rs=1/R1+1/R2+1/R3

V = V1+ V2 +V3

I = I1 +I2+ I3

I=Q/t

P=W/t
