0.2A

Answer 1

Given:

• Resistance = 7.50 Ω
• Potential difference = Voltage = 1.5 V

To find:

Current = ?

Method:

Applying Ohm's law,

The potential difference across ends of a metallic wire in an electric circuit is directly proportional to the current flowing through it, provided it's temperature remains same

Voltage is directly proportional to Resistance

⇒V = IR

⇒I = V ÷ R

⇒I = 1.5 ÷ 7.50

⇒I = 0.2 A

∴ Current = 0.2 A

Answer 2

Answer:

0.2 A

is the answer....
