Problem: The voltage and current at the terminals of the circuit element in Fig 1.5 are zero for t < 0. For t > 0 they area) Find the maximum value of the power delivered to the circuit.b) Find the total energy delivered to the element

FREE Expert Solution

Power in the circuit is expressed as:

P=Vi, where V is voltage and i is current.

Total energy delivered to the element is found from:

w=0p(t)dt

a)

From the equation for power:

P=Vi=(75-75e-1000t)(50e-1000t×10-3)=3.75e-1000t-3.75e-2000t
