Question

find the voltage V in the given figure​

Answer 1

Answer:

30V

Net resistance=30

Current=50/10

=5A

Potential drop across the circuit=IR

5*4=20V

So 50V-20V is the correct answer.

Answer 2

Given:

Resistances= 4Ω, 6Ω

To find:

The voltage in the circuit

Solution:

The voltage in the circuit is 30V.

We can find the voltage by following the given steps-

We know that the voltage can be obtained as a product of the current flowing in the circuit and the resistance.

V=IR, where V is the voltage, I is current, and R is the resistance.

We are given the value of R as 6Ω and 4Ω.

We will calculate the current as follows-

I=V/R

I=50/(4+6)

I=50/10

I=5A

Now, the voltage=current×resistance.

V=5×6

V=30V

Therefore, the voltage in the circuit is 30V.
