Question

a resistor having a resistance 6.2 Ohms is connected across a battery of 5V using a wire of negotiable resistance.the current passing through the resistor is 0.4A.what is the total power produced by the battery?

Answer 1

Answer:

power = VI

power = 5 × 0.4

power = 2W.

Answer 2

Answer:

The total power produced by the battery is 2 Watts.

Explanation:

From the question, we have the following given values,

The resistance of the resistor=6.2Ω

The potential difference across the battery=5 volt

The current passing through the resistor=0.4A

• Electric power is a unit of measurement for how quickly electrical energy is transferred over an electric circuit.
• The battery's power is determined as follows:

                                    $\mathrm{P=V\times I}$         (1)

Where,

P=power consumed by the battery

V=potential difference across the battery

I=current flowing

By placing the required entities in equation (1) we get;

                                $\mathrm{P=5\times 0.4}$

                                $\mathrm{P=2\ W}$

So, the total power produced by the battery is 2 Watts.
