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
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!
The correct option is B (30V)
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
