Question

please give solution​

Answer 1

Answer:

• Vb = VccR2R1+R2 and.

• That is valid if R1R2R1+R2 << βRe.

• Rx = R1R2R1+R2.

• V1 = VccR2R1+R2.

Answer 2

• The voltage will be that of the highest battery voltage.

• The battery will try to charge the batteries with lower voltage resulting in very large currents flowing from the high voltage battery.
