Question

if a 24 volt and 10 volt battery are series opposing then total voltage is A.14 B.34 C.24 D.10. Explain it

Answer 1

Answer:

In a series Connection, all the devices connected have variable resistance and variable potential differences. Hence in series the only thing that remains unchanged is current in the system.

So to calculate Net current we dont have to add up all current as we have same current throughout the circuit. But for Potential Difference and Resistance we must add up all the values given to calculate the net value.

According to the question, values given are 24 V and 10 V.

So Net Voltage would be adding up the values. Which is:

⇒ 24 V + 10 V = 34 V

But since it is in the opposite direction we must add a negative sign to 10 so that we get a positive value for the Potential Difference.

Hence the Net voltage is 24 - 10 = 14 V

Hence Option A is correct.

Hope it helped !!

Answer 2

If a cell connects a series negative terminal of the cell a connected to a positive terminal of an another cell. By applying a sign conversion rule to this circuit you get an answer☆

As V1 = 24 volt V2 = 10 volt but V2 is Negative

V1-V2 = 24-10 = 14volt

total opposing voltage is 14 volt
