Question

what potential difference Must be applied across a 10 ohm wire in order that a current of 2.5 A ampere flows through it

Answer 1

Answer:

25 V

Explanation:

V = IR

I = 2.5 A

R = 10 Ώ

V = IR = 10 x 2.5 = 25 V

Answer 2

Potential Difference = 25 Volts

Explanation:

Potential difference: It is defined as the difference in the electric potential of the two bodies.

it's symbol is V. It's SI unit is Volt.

By using Ohm's Law.

                            V = IR

Here V = Potential Difference

         I = Electric current

         R = Resistance

According to the question,

V = ?

I = 2.5 A

R = 10 Ohm

Putting the values in formula

V = 2.5 × 10

V = 25 Volts
