Download Solution PDFThe energy consumed by a 5Ω resistor carrying a 20A current in 10 minutes will be _______
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFEnergy: It is the ability to do work.
According to the laws of conservation of energy, “ energy can neither be created nor destroyed but can only be converted from one form to another”. The SI unit of energy is Joule.
The energy is the product of power and time.
E = P × t
E = I2 × R × t
where, E = Energy
I = Current
R = Resistance
t = Time
Calculation
Given, R = 5Ω
I = 20A
t = 10 minutes = 600 sec
E = (20)2 × 5 × 600
E = 1200 KJ
