For redundancy in case of failure or for connecting them to different subnets.
We know, Voltage drop = Voltage * Resistor / total resistance
Here, voltage = 75 V
Resistor for cal. = 10 Ohm
Total resistance = 10 + 15 = 25 Ohm
Substitute their values,
e = 75 * 10/25
e = 3 * 10
e = 30 V
In short, Your Answer would be Option B
Hope this helps!
<h2>eXclusive OR</h2>
<h3>✅X. (eXclusive OR) A Boolean logic operation that is widely used in cryptography as well as in generating parity bits for error checking and fault tolerance. XOR compares two input bits and generates one output bit. The logic is simple. If the bits are the same, the result is 0.</h3>
