Question

Calculate the voltage if the current is 0.5 A and the resistance is 2.0 Ω.

Answer 1

1 V

Step-by-step explanation:

Voltage = current x resistance

V = 2 x 0.5

V = 1

Answer 2

1V

Step-by-step explanation:

Here we would be using Ohm's law to calculate the voltage. Remember that voltage is also known as potential difference.

★ Ohm's law :

• V = IR

Here,

• V is potential difference
• R is resistance

We have :

• V = (0.5)(2)
• V = 5/5
• V = 1V
