![]() ![]() The unit of resistance is the ohm, and the measuring instrument of the resistance is a multimeter. The Resistance is defined as, it is the opposition that a substance offers to the flow of electric current. Please refer to this link to know more about alternating current and voltage MCQs And, current gets distributed when components are connected in parallel. The flow of current is same in all the components which are connected in series. The measuring instrument of the current is an ammeter. The unit of current is amps or amperage and 1 ampere =1 coulomb/second. The current is defined as it is the rate of flow of electric charge in a circuit. The voltage gets distributed over different electronic components which are connected in series in the circuit, and in parallel circuit voltage is same across all components which are connected in parallel. ![]() Voltage is the source and the current is its result, it can occur without current. The measuring instrument of voltage is the voltmeter. Resistance is the electric property that impedes a current. The term volt is represented by the letter V in schematics. Resistance: The electrical resistance of an object is a measure of its opposition to the flow of electric current. The unit volt is termed after invented by Italian physicist Alessandro Volta. (V=W/C)).One point has more charge than another. It is measured in volts (1V = 1 joule/coulomb. The voltage is defined as, it is the potential difference in charge between the two points on a circuit, it is also called electromotive force. Please refer to this link to know more about Ohms Law MCQs The difference between voltage and current and resistance is discussed below. He described a unit of resistance which is defined by voltage and current. The major components used in the circuit let us to control the charge and use it to do the work.So, Bavarian scientist “Georg Ohm” was studied electricity. So, when we discuss about these values, the behavior of electrons in a closed loop circuit allows charge to move from one place to another.
