Question

15 C charges flow for 3 second and resistance in circuit is 5 ampere. Find Potential difference. ​

Answer 1

Answer:

The Potential Difference is 25 V.

Explanation:

Given,

Electric Charge (Q) = 15 C

Time (t) = 3 s

Resistance (R) = 5 ohms

Electric Current (I) = Q/t

= 5 A

= Potential Difference (V) = R = V/I

= 5 = V/5

= 25 V = V

Hope this helps.

Answer 2

Correct Question

✪ 15 C charges flow for 3 second and resistance in circuit is 5 ohms. Find Potential difference.

Given

➛ Charge moving (Q) = 15 C

➛ Resistance (R) = 5Ω

➛ Time (t) = 3 s

To find

➛ Potential difference of circuit

Solution

Now we have,

⎆ Charge (Q) = 15 C

⎆ Time (t) = 3 s

⎆ Resistance (R) = 5Ω

Now we know the Coulomb's law :

✭ I = Q/t

Where,

• I denotes current flowing
• Q denotes Charge moving
• t denotes Time

Substituting values,

⇒ I = 15/3

⇒ I = 5 A

Now we know Ohm's law :

✭ V = I * R

Where,

• V denotes potential difference
• I denotes current
• R denotes resistance

Substituting values,

⇒ V = 5 * 5

⇒ V = 25

⇒ V = 25 volts.

∴ Potential difference of circuit = 25 v
