Question

An electric work of 6 megajoule is done when electric current flows through a circuit at potential difference of 250 V for 1 hour. find the current flowing through electric current​

Answer 1

Explanation:

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.

Answer 2

Answer:

The current flowing through electric current is 6.67 A.

Explanation:

Given:

• Electric work (W) = 6 M.J.

• Potential difference (V) = 250 V

• Time (t) = 1 hr

To find:

Electric current (I) flowing through electric circuit.

Solution:

1 megajoule = 1,000,000 Joule

so, Electric work (W) = 6 M.J = 6,000,000 J

Time (t) = 1 hr = 3600 s

Now we know that,

W = I × V × t

⟹ 6,000,000 = I × 250 × 360

⟹ I = 6,000,000/250*360

⟹ I = 6.67 A

Hence, solved!!
