choose the correct option from the following statements: iii. Ageing, temperature, weather are factors of. ( weak of protection- weak of insulation-none of them) is the most commonly used protective device in a distribution circuit. (Fuses - Circuit breaker - Relay) faults in power systems with more than 80% of the occurring faults is .............. (Temporary Faults- Permanent Faults - none of them) iv. expressed as a fraction, is the ratio between the magnitudes of the primary and the secondary current for ideal working conditions of the curren transformer. (The knee point- Current Transformer Ratio (CTR) - Over-current relay) V. ........is the most widely used over-currrent characteristics. (Definite Time - Instantaneous-Inverse Definite Minimum Time Relay) give me the choice only ( final answer )

What will be the permeability of a magnetic material if it has amagnetization of 2350 A/m and it produces a flux density of3.142 mWb/m2.B 1 20 x 10-5 H/m 2 x 10-5 H/m 20 x 10-7 H/m 2 x 10-5 Hm
