At a voltage of 70 V, the current in the conductor is 1.4 A Determine its resistance.

Given:

U = 70 Volts – electrical circuit voltage;

I = 1.4 Amperes – the strength of the current passing through the conductor.

It is required to determine R (Ohm) – the resistance of the conductor.

To determine the resistance of a conductor, you must use the following formula (Ohm’s law):

U = I * R, from here we get that:

R = U / I;

R = 70 / 1.4 = 700/14 = 50 Ohm.

Answer: the resistance of the conductor is 50 Ohm (0.05 kOhm).
