WebRemember, current tells us the rate of movement of charge. Whilst potential difference tells us the energy transferred per unit charge. Therefore to find the total energy transferred per second, power, you need to multiply current by voltage. Power is measured in Watts (W). 1W means 1J of energy transferred in 1 second. Web21 Dec 2024 · Ohm's Law is one of the basic laws of physics. It describes relationship between voltage, amperage (otherwise known as current) and resistance. Voltage refers to the potential difference between two points in an electrical field. Amperage is related to the flow of electrical charge carriers, usually electrons or electron-deficient atoms.

WebImportant Points. 1. Although we call e.m.f. as force but actually it is energy which is given by the cell to unit charge for flowing through the circuit. 2. If external resistance is connected between the terminals of the cell the the potential difference between the terminals is 'Terminal voltage' of the cell. 3. WebOhm’s Law. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is electric potential difference, and R R is resistance.
