Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A resistor having resistance 6.2 is connected across a battery of 5 V by means of a wire of negotiable resistance. Current passes through resistor is 0.4 A. total power produced by battery is

A	2 W
B	3 W
C	5 W
D	6 W

Explanation:

Detailed explanation-1: -Answer and Explanation: Thus, the current flowing in the circuit is approximately 0.002 A.

Detailed explanation-2: -When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x .

Detailed explanation-3: -The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. Charge flows at the greatest rates when the battery voltage is increased and the resistance is decreased.

Detailed explanation-4: -Ohm’s Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm’s Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you know the voltage of the battery in the circuit and how much resistance is in the circuit.
