A dc voltage source of 12 V is connected in series with 3 resistors of 3 Ω \Omega , 4 Ω \Omega and 5 Ω \Omega one by one. 3 Ω \Omega resistor is connected with the positive side of the voltage source. An ideal diode is connected in parallel across 4 Ω \Omega resistor with anode side in 3 Ω \Omega resistor direction. What will be the voltage drop across 5 Ω \Omega resistor?
