Answer 2

Answer

Given:

Charge (Q) = 0.5 Coulombs

Time (t) = 0.2 seconds

Potential Difference = 10 V

Find:

The current (I) and resistance (R) of the wire.

Solution:

The above numerical can be solved by using the formula,

Current = Charge/ Time

I = $\frac{Q\\}{t}$

By substituting the values we get,

Current = $\frac{0.5}{0.2}$

⇒ I = 2.5 A

After getting current, we can easily find the resistance of the wire by using the formula,

Resistance = Voltage/ Current

R = $\frac{V}{I}$

By substituting the values we get,

Resistance = $\frac{10}{2.5}$

⇒ R = 4 ohms

This will be considered as the final answer. As the SI unit of resistance is Ohm (Ω), we have to use the SI unit for the final answer also. And, the SI unit of current is Ampere (A).

Hence, the current of the wire is 2.5 A and the resistance of the wire is 4 ohms.
