Consider the following incomplete statement "Ohm's law relates potential difference with ...... for a given resistance". The suitable choice for the missing word is (a) power (b) energy (c) current (d) time

You have three resisters of 9 ohms each. By combining them what can be (a) the highest resistance, and (b) the lowest resistance? (c) How can you combine them to get a resistance of \(12 \Omega ?\)

Two resistors of \(5 \Omega\) and \(10 \Omega\) are connected in series in a circuit. How does the current passing through them compare?

Consider the following statements: A. In series connection, the same current flows through each element. B. In parallel connection, the same potential difference gets applied across each element. (a) both \(\mathrm{A}\) and \(\mathrm{B}\) are correct (b) \(\mathrm{A}\) is correct but \(\mathrm{B}\) is wrong (c) \(\mathrm{A}\) is wrong but \(\mathrm{B}\) is correct (d) both \(\mathrm{A}\) and \(\mathrm{B}\) are wrong
