Answer 1

Answer:

94 V

Explanation:

Here we don't have the figure showing the circuit and how the resistors are connected: therefore, we have to make some assumptions.

Here we will assume that the three resistors are connected in series: this means that they are connected along the same branch, and therefore, the current flowing through them is the same.

As a result, the total voltage drop across some resistors in series is given by the sum of the voltage drops on each resistor.

Therefore, for three resistors in series

$V=V_1+V_2+V_3$

Where here we have:

$V_1 = 56 V$ is the voltage drop on the 1st resistor

$V_2=35 V$ is the voltage drop on the 2nd resistor

$V_3=3 V$ is the voltage drop on the 3rd resistor

Substituting into the equation, we find:

$V=56+35+3=94 V$
