Question

Please show steps for solving this question. Specifically addressing how to write the KVL equations when the current and voltage + and - seem to contradict. For example, I think Ic should drop voltage when going up over the resistor. Is it ok to change the current reference direction before solving or would that throw off the answer?

2) For the circuit shown, find the value of Iq, Ib, Ic and Va: Hint: substitute the result from KCL into two KVL equations to get two equations with two unknowns. Іa I, 20 Ohms 20 Ohms le 20 Volts © 2012 Va >10 Ohms
