# Three 50 Ohms resistors R1, R2 and R3 are in series across an applied voltage of 180 V. How much is the IR voltage drop across each resistor?

# Given data

R1 = 50*10**3#       # Resistor 1=50k Ohms
R2 = 50*10**3#       # Resistor 2=50k Ohms
R3 = 50.*10**3#       # Resistor 3=50k Ohms
Vt = 180.#           # Applied Voltage=180 Volts

R = R1              # R = R1 = R2 = R3
Rt = R1+R2+R3#
V = Vt*(R/Rt)#
print 'The Voltage Drop across each Resistor = %0.2f Volts'%V
The Voltage Drop across each Resistor = 60.00 Volts
