Question

Calculate the voltage if 20A of current flows for 100 sec with 200J of work

Answer 1

Answer:

0.1 Volts

Explanation:

Given:

• Current passing through the circuit = I = 20 Amperes
• Time taken = t = 100 seconds
• Work done = 200 joules

To find:

• Voltage or potential difference across the circuit

Using the forumla:

q=i×t

Where,

q=Charge

i=Current

t=Time taken

Substituting:

q=20×100

q=2000 Coulombs

Work = potential difference×Charge moved

200 = V×2000

V = 0.1 Volts

The voltage across the circuit is equal to 0.1 Volts

Answer 2

⭐ Given :-

• Current = 20 Amperes.
• Time = 100 seconds.
• Work Done = 200 Joules.

⭐ To Find :-

• Voltage.

⭐ Solution :-

Use Formula,

Charge = Current × Time.

☞ Charge = 20 × 100.

☞ Charge = 2000 Coulombs.

Now, Use Formula,

Work = Potential Difference × Charge.

☞ 2000 = V × 20.

☞ V = 0.1 Volts.

Hence, Your Answer is 0.1 Volts.
