#1

\\ \rm\dashrightarrow P=VI\implies V=\dfrac{P}{I}

\\ \rm\dashrightarrow V=\dfrac{0.4\times 10^3}{33\times 10^{-3}}

\\ \rm\dashrightarrow V=0.012\times 10^{-6}

\\ \rm\dashrightarrow V=12mV

#2

\\ \rm\dashrightarrow R=\rho \dfrac{\ell}{A}

\\ \rm\dashrightarrow \rho =\dfrac{RA}{\ell}

\\ \rm\dashrightarrow \rho=\dfrac{86.3(0.4\times 10^6)}{69}

\\ \rm\dashrightarrow \rho=0.5\times 10^{6}

  • It should be silicon

#3

Ohms law

\\ \rm\dashrightarrow R=\dfrac{V}{I}

\\ \rm\dashrightarrow R=\dfrac{7(10^3)}{6(10^{-6})}

\\ \rm\dashrightarrow R=1.167\times 10^9\Omega
