Define one ohm meter class 10
WebThat is, volts = amps x ohms. R stands for resistance in this formula. If resistance is unknown, the formula can be converted to R = E/I (ohms = volts divided by amps). In the first example, total normal circuit resistance, a known reference value, is 60 Ω (240 ÷ 4 = 60 Ω). The 60 Ω resistance can help determine the condition of a circuit. WebFeb 9, 2024 · (ii) The unit of resistivity is ohm meter. Question 5. Define the unit of resistance? (or) Define one ohm. Answer: The resistance of a conductor is said to be one ohm if a current of one ampere flows through it when a potential difference of one volt is maintained across its ends. \(\text { Ohm }=\frac{1 \text { volt }}{1 \text { ampere ...

S.I. unit of resistivity is ohm meter ( Ω⋅m ). ρ, is independent of the dimensions of the conductor. It depends on the electron density of the conductor and the relaxation time.
WebWell, I can rearrange this formula, and I can get that the resistivity equals the resistance times the area of the resistor divided by the length. And so that gives me units of ohms times meters squared, 'cause that's area, divided by meters. And so I end up getting ohms. One of these meters cancels out.
