With a series connection of three resistances connected to the battery, the voltage on the first resistance

With a series connection of three resistances connected to the battery, the voltage on the first resistance is 66 ohms to the winding 87 ohms, 56 ohms. What is the voltage on the third resistance, if the total voltage is 200v, determine the total resistance and current in the circuit.

1. When connected in series, the total resistance of the circuit is equal to the sum of the resistances of the individual sections. Thus, the total resistance will be equal to:

Rtot = R1 + R2 + R3 = 66 +87 +56 = 209 Ohm

2. The current in the circuit, according to Ohm’s law:

I = Utot / Rtot = 200/209 = 0.96 A

3. Voltage at the third resistance:

U3 = I * R3 = 0.96 * 56 = 53.76 V
