An open coil has
A. zero resistance and inductance
B. infinite resistance and zero inductance
C. infinite resistance and normal inductance
D. zero resistance and high inductance
Answer:B
An open coil has
A. zero resistance and inductance B. infinite resistance and zero inductance C. infinite resistance and normal inductance D. zero resistance and high inductance
Explanation: Here Coil is open coil I=0 so R =V/I = V/0 = Infinite and Inductance L = di/dt = 0/dt = 0. so Inductance Zero and Resistance is infinite.
