Question

A laptop computer draws 5 A of current with a voltage of 19 V. Which is the power used by the computer?

15 W
95 W
0.26 W
3.8 W

Answer 1

Answer : The power used by the computer is, 95 W

Solution : Given,

Current = 5 Ampere

Voltage = 19 Volt

Power : It is defined as the product of the voltage and the current in the circuit.

Formula used :

`P=V* I`

where,

P = power

V = voltage

I = current

Now put all the given values in the above formula, we get the power used by the computer.

`P=V* I=(19V)* (5A)=95watt=95W`

Therefore, the power used by the computer is, 95 W

Answer 2

There are several information's of importance already given in the question. Based on those information's the answer can be deduced.
Volage = 19 V
Current = 5 A
Power = Voltage x Current
= 19 x 5
= 95 Watt
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or 95 W.
