Volt - Unit of Electrical Potential or Motive Force - Potential is Required to send One Ampere of Current Through one ohm of Resistan
Ohm - Unit of Resistance - One (ohm) is The Resistance offered to The Passage of One Ampere when impelled by one Volt
Ampere - Units of current - one ampere is the current which one Volt Can send through a Resistance of one ohm
Voltage V = I × R = P / I = √(P × R) in volts ---- (V)
Current I = V / R = P / V = √(P / R) in amperes ---- (A)
Resistance R = V / I = P / I2 = V2 / P in ohms -----(Ω)
