Question

Calculate the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.​

Answer 1

Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.

Step-by-step explanation:

• The rate of energy transfer from one point to another is known as power.
• Its SI. unit is Watt.

Formula to compute power:

Power =
`I^2 R`, I = cureent, R = resistance.

Given R = 5 ohm , Current = 0.5 A.

Then, power =
`(0.5)^2* 5=0.25*5=1.25\ watt`

Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
