C. 1000 ohms
D. 5000 ohms
Answer: Option D
This Question Belongs to Electronics And Communications Engineering >> Electromagnetic Induction
A. Self-inductance
B. Mutual inductance
C. Series aiding inductance
D. Capacitance
Which circuit element(s) will oppose the change in circuit current?
A. Resistance only
B. Inductance only
C. Capacitance only
D. Inductance and capacitance
Which of the following circuit elements will oppose the change in circuit current?
A. Capacitance
B. Inductance
C. Resistance
D. All of the above
this formula is from chap 7 (I RMS =v naught /xL) xL=v/i=50/10^-2=5000
M = -e/rate of change of current or value of given
Current
So, M = 50/5×10^-3
M= 5×10^3=5000 ohms
I=V/XL, xl=v/i=50/(10/1000)=50000/10=5000
How?
