A resistor is connected in series with a power supply of 20.00 V. The current measure is 0.50 A. What is the resistance of the resistor

40 Ω

Explanation:

The following data were obtained from the question:

Potential difference (V) = 20 V

Current (I) = 0.50 A

Resistance (R) =?

From ohm's law:

V = IR

Where:

V is the potential difference.

I is the current.

R is the resistance.

With the above formula, we can obtain the resistance of the resistor as follow:

Potential difference (V) = 20 V

Current (I) = 0.50 A

Resistance (R) =?

V = IR

20 = 0.5 × R

Divide both side by 0.5

R = 20/0.5

R = 40 Ω

Therefore, the resistance of the resistor is 40 Ω

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
