Answer 1

Answer:

• 1.8×10⁶ Joules is the required answer.

Explanation:

Given:-

• Power Of Lamp ,P = 100 W
• Time used for ,t = 5 hr = 5×60 × 60 = 18000 s

To Find:-

• Energy Consumed ,E

Solution:-

As we have to calculate the energy consumed by lamp in one day which is used for 5 hours daily.

Energy consumed is defined as the amount of power used by appliances .

It can be calculated by the product of Power of Appliances & Time taken.

• E = P× t

where,

• E denote Energy Consumed
• P denote Power
• t denote time taken

substitute the value we get

→ E = 100× 18000

→ E = 1800000

→ E = 1.8 × 10⁶ J

• Hence, the energy consumed by the Lamp is 1.8×10⁶ Joules.

Answer 2

Answer:

Given :-

• Power = 100 watt
• Time = 5 × 60 × 60 = 18000 s

To Find :-

Energy consumed

Solution :-

Here, we will use the formula for finding energy

$\boxed{ \bf \: E = P \times T}$

E is the Energy consumed

P is the Power

T is the Time

Let's calculate

E = 100 × 18000

E = 1800000

Now,

E = 1.8 × 10⁶ Joules

Hence :-

Energy consumed by lamp is 1.8 × 10⁶ Joules.
