Detailed explanation-1: -Expert-Verified Answer. Answer : The unit of resistance is ohm and it is equal to volt ÷ ampere.
Detailed explanation-2: -Voltage is measured in volts, symbolized by the letters “E” or “V”. Current is measured in amps, symbolized by the letter “I”. Resistance is measured in ohms, symbolized by the letter “R”. Ohm’s Law: E = IR; I = E/R; R = E/I.
Detailed explanation-3: -The ohm is a measurement of resistance between two points of a conductor when a constant potential difference of one volt (V) is applied to those points and a current of one ampere (A) is produced. In simpler terms, it’s the equivalent of one volt per one ampere (V/A).
Detailed explanation-4: -Ohm’s law states that current is directly proportional to voltage and inversely proportional to resistance. The voltage, current, and resistance formula is expressed as I=VR I = V R, where I is the current in amperes (A), V is the voltage in volts (V), and R is resistance in ohms ( ).
Detailed explanation-5: -The unit of current is the ampere (A), and means one coulomb per second. The unit of potential difference is the volt (V), and means one joule per coulomb. The unit of resistance is the ohm (), and is equal to voltage over current.
