Question

По проводнику течет ток силой 2А разность по потенциалов на концах проводника 20В чему ровно сопротивление проводника

Answer 1

Закон Ома I=U/R
R=U/I R=20/2=10

Answer 2

Calculating the Resistance of the Conductor

To calculate the resistance of the conductor, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points. The formula for Ohm's law is:

V = I * R

Where: - V = Voltage across the conductor (20V) - I = Current flowing through the conductor (2A) - R = Resistance of the conductor (to be calculated)

We can rearrange the formula to solve for the resistance (R):

R = V / I

Substituting the given values: R = 20V / 2A = 10Ω

Therefore, the resistance of the conductor is 10 ohms.
