Four 50 ohms are connected in series calculate the current in the circuit?

The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms.

In electronics, R or resistance is calculated by dividing the voltage by the current, or I/E Here's a good Ohms law chart; http://www.the12volt.com/ohm/ohmslaw.asp


According to george Simon ohm what is the relationship between current voltage and resistance and how can it be calculated?

Ohm's Law is stated as V=I*R, where V = voltage, I = current, R = resistance.
