E = 600 J

Explanation:

Given that,

Voltage, V = 10 V

Current, I = 2 A

Time, t = 30 s

We need to find the energy transferred. Energy transferred is calculated as follows :

E=I^2Rt

Ohm's law, V = IR, R = V/I

$E=I^2\times \dfrac{V}{I}\times t\\\\E=IVt\\\\E=2\times 10\times 30\\\\E=600\ J$

So, 600 J of energy is transferred.
