Answer:
current in the circuit is 1.428 A
Explanation:
Given data
voltage = 60 V
resistor = 21 Ω
time = 0
to find out
current in the circuit
solution
we have given that
voltage across the resistor = voltage across the inductor
that is = 60 /2 = 30 V
we know voltage across resistor = IR
so I × R = V/2
and current I = 30 /21
so current = 1.428 A
current in the circuit is 1.428 A
The model is based on hypothesis to get an initial idea for analyzing a complex problem. Hence, the validity of a model is limited and may not be valid universally. On the other hand, theories and laws are confirmed hypothesis which are universally valid. These are formulated after repeated testings. theories are more explanatory.
