v/r=i
v/50Ω+50Ω+50Ω+50Ω=i
v/200Ω=i

u need voltage to do this !

The total resistance is 200 ohms and if the voltage is 220 volts, the current is 220 / 200 = 1.1 ampere and if the voltage is 110 volts, the current is 0.55 amperes.

Formula is Curent = Voltage / Resistance.

If any inductance is present in the circuit the effective current changes.

ohm's law
i = square root of p divided by r
i = p divided by e
i = e divided by r

you're looking for i but have two unknown variables
