Q.

Three resistors are connected to a $12V$ battery as shown in the figure given below :

1. What is current through $8\mathrm{ohm}$ resistor?
2. What is the potential difference across the parallel combination of $6\mathrm{\Omega }$ and $12\mathrm{\Omega }$ resistor?
3. What is the current through $6\mathrm{\Omega }$ resistor?

Q.

Consider the circuits shown in the figure. The magnitude of the ratio of the currents, i.e, $\left|I_1/I_2\right|$, is

1. 1

Q. Consider the two-port resistive network shown in the figure. When an excitation of 5 V is applied across port 1, and port 2 is shorted, the current through the short circuit at port 2 is measured to be 1 A (see(b)in the figure).

Now, if an excitation of 5 V is applied across port 2, and port 1 is shorted (see(b) in the figure), what is the current through the short circuit at port 1 ?

1. 0.5 A
2. 2.5 A
3. 1 A
4. 2 A
