Question

calculte the potential difference required to pass a current of 5A through a metallic rod of resistance 10 ohm

Answer 1

Answer:

50 volts

Explanation:

given:I=5A. R=10

V=5x10

=50volt

Answer 2

The potential difference (V) required to pass a current of 5 A through a metallic rod of resistance 10 ohms can be calculated using Ohm's law, which states that V = IR, where I is the current in amperes and R is the resistance in ohms.

So, the potential difference V = IR = 5 A × 10 Ω = 50 V.

Therefore, the potential difference required to pass a current of 5 A through a metallic rod of resistance 10 ohms is 50 V.

• Ohm's law states that the potential difference (V) across a conductor is directly proportional to the current (I) flowing through it, for a given temperature and other constant parameters, provided that the conductor is a good conductor. This can be mathematically represented as V = IR, where R is the resistance of the conductor.
• In the case of a metallic rod with a resistance of 10 ohms, if a current of 5 A is flowing through it, the potential difference required can be calculated using the equation V = IR. Substituting the values, we get V = 5 A × 10 Ω = 50 V.
• Therefore, to pass a current of 5 A through a metallic rod of resistance 10 ohms, a potential difference of 50 V is required. This is because the potential difference drives the current through the conductor, and it is proportional to the current and the resistance of the conductor, as stated by Ohm's law.
