Explanation:
Since the current flowing through an ideal capacitor is described by equation:
for voltage across the capacitor constant with time the current is:
Open switch has this characteristics (Constant voltage and zero current).
Answer:
The current in the motor in this case is 13.2 A
Explanation:
Given:
Resistance 5 Ω
Emf V
Induced emf V
When motor run at half speed due to load increased then induced emf is also reduced to half of its value
So new induced emf in our case is given by,
V
Where
A
Therefore, the current in the motor in this case is 13.2 A
