A series circuit contains a generator, two devices, and connecting wires. The resistances of the two devices are 15 ohms and 10 ohms. The voltage supplied by the generator is 75 V. What will be the voltage drop in the device with 10 ohms of resistance? A. 25 V B. 30 V C. 3 V D. 45 V

Verified Answer :

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!

Answer:

The correct option is B (30V)

Explanation:

We know, Voltage drop = Voltage Resistor/all out obstruction  

Here, voltage = 75 V  

Resistor for cal. = 10 Ohm  

Complete obstruction = 10 + 15 = 25 Ohm  

Substitute their qualities,  

e = 75 10/25  

e = 3 * 10

e = 30 V
