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?

Verified Answer :

Maybe you can apply the Ohms law to this question:

Ohms law is voltage=current (I) x resistance (R)

I'm afraid that is the only concept i know abt electricity. i hope u find a solution;)

Answer:

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
