Question

a wire having resistance of 20 ohm, carrying current of 9 ampere. what is the potential difference across its ends?​

Answer 1

Explanation:

V=IR

I=9A

R=20OHM

V=20×9=180V

Answer 2

Given :

• Resistance = 20 Ohms

• Current = 9 A

Solution :

Use Ohm's law :

⇒ V = IR

⇒V = 20 * 9

⇒ V = 180

➜ Potential difference is 180 V.
