[Note: Enter the answers up to two decimal places by rounding off the third decimal value].

$t$

$=$

$2\ hour$

On converting hour to second, we get

$t$

$=$

$s$

The formula for power is

$i = i \times i$

On substituting the given values, we get

$W$

The formula for electrical energy is

$i = i \times i$

if it is used for hour $=$ $\times {10^{6}}$ $J$

$1$
