Question

The practical unit of resistance is $\Omega$ and 1$\Omega$ is equal to :

• A. ${10}^{18}emu$
• B. ${10}^{9}emu$
• C. ${10}^{15}emu$
• D. none of these

Answer 1

Answer: (B)

${10}^{9}emu$

The ohm (symbol: $\Omega$) is the SI derived unit of electrical resistance.

And 1 ohm = 1000000000 EMU of resistance = ${10}^{9}emu$
