# Voltage time graph integration

In a Voltage time graph , at constant current I= 170 amps, voltage=0 to 5,5 and time= 0 to 97 sec and voltage decreases from 5,5 at 0sec to 1,16 at 97 sec, now how can I find the total power consumption wrt time in this case and in a compley system how can we find power losses in the cables or circut please some one help me out. Thank you

• Welcome to EE.SE. Please add the graph into your question and fix the punctuation, show your work so far and where you are stuck. – Transistor Jul 5 '18 at 11:56
• Instantaneous power is the (instantaneous) product of voltage and current. When you ask "how much is the power input to the circuit" and "how can we find power losses in the system", it's like asking if it's raining at your hometown without telling us where is your hometown. If it's more of a "theoretical question", then keep in mind that energy conservation is a thing. – Vicente Cunha Jul 5 '18 at 12:18
• I was trying a resistive heating on a material – Pru Jul 5 '18 at 12:28
• That doesn't show the work you did, only a repetition of the problem, on paper. – a concerned citizen Jul 5 '18 at 13:09
• But how can we do integration of that shaded area? – Pru Jul 5 '18 at 13:52
