[3 marks] Label direction of the current and polarity of all voltages across each resistor. Use voltage division to find the value of \( \mathrm{V}_{1} \) in the circuit below. \[ \begin{array}{l} V_{5}=24[\mathrm{mV}] \\ R 1=4[\Omega] \\ R 2=8[\Omega] \\ R 3=12[\Omega] \end{array} \] [3 marks] Label direction of all currents and polarity of all voltages across each resistor. Use current division rule to find the value of \( \mathrm{I}_{2} \) in the circuit below. \[ \begin{array}{l} I_{5}=2[\mathrm{~mA}] \\ R 1=3[\mathrm{k} \Omega] \\ R 2=6[\mathrm{k} \Omega] \end{array} \]
