Dimensional formula of electrical resistance
WebThermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow.Thermal resistance is the reciprocal of thermal conductance. (Absolute) thermal resistance R in kelvins per watt (K/W) is a property of a particular component. For example, a characteristic of a heat sink.; Specific … WebThe formula for Resistance according to Ohm's law is given as, R = V I Where, V is the potential difference, and I is the electric current. The formula for potential difference is, V = E L Where, E is the electric field, L is the length between the two points in a conductor. The formula for electric field is, E = F q
