Question

If the resistance of a conductor is 2 ohm is
connected to 5 v cell then current flowing through
the circuit is
А. ЗА
B. 25 A
C.3.5 A
D. 4 A​

Answer 1

Explanation:

V = IR

I = V/ R

= 5/2

= 2.5 A

= 3 A (approximately)

Answer 2

Given :-

• The resistance of a conductor is 2 ohm is
• connected to 5 v cell

To find :-

• Current following through circuit.

Solution :-

• Resistance = 2 ohm

• Potential difference = 5V

According to Ohm's law

The law states the current flowing through a conductor is directly proportional to the potential difference across the ends of conductor provide the temperature and other physical condition remains the same.

• V = IR

Where " V " is potential difference, " I " is current and " R " is resistance.

According to question

→ V = IR

Now put values

→ 5 = I × 2

→ I = 5/2

→ I = 2.5A

Hence,

• Current flowing through conductor is 3A(approx)
