Question

5. What is the potential difference if a resistance of 25 ohms produces a

current of 250 amperes?

Answer 1

Using Ohm's Law, the potential difference needed to produce a current of 250 amperes through a 25-ohm resistance is calculated to be 6250 volts.

Step-by-step explanation:

Ohm's Law and Calculating Potential Difference

The student has asked: What is the potential difference if a resistance of 25 ohms produces a current of 250 amperes? To answer this question, we use Ohm's Law, which states that the potential difference (V) across a resistor is equal to the product of the current (I) flowing through that resistor and its resistance (R). Mathematically, this relationship is expressed as:

V = I × R

Given:

• Resistance (R) = 25 ohms
• Current (I) = 250 amperes

Using these values:

V = 250 A × 25 Ω = 6250 V

So, the potential difference that would produce a current of 250 amperes through a 25-ohm resistor is 6250 volts.

Answer 2

Voltage (v) = 250 V

Resistance (R) = 25 Ω,

Determine current (I) =?

We know that from ohm's law

V = I R

I = V/R

I = 250 / 25

I = 10 A

Current in the circuit is 10 Amps
