B1. a) For the circuit given in Figure B1.1, use loop current method and find the voltage across \( 10 \Omega \) resistor, i.e., \( V_{10} \). [8 marks] b) In Figure B1.1, if we change the value of current source to \( 5 \mathrm{~A} \) and voltage source to \( 20 \mathrm{~V} \), what is the voltage across \( 10 \Omega \) resistor now? [5 marks] c) In Figure B1.2 below, choose which method out of node voltage or loop current is more suitable. Then apply that method to compute \( i_{o} \) and \( v_{o} \). (Hint: compare the number of essential nodes and number of loops to choose which method is best suitable). [11 marks] Figure B1.2
