Electrical Cables A certain cable has an insulation of relative permittivity 4. If the insulation is replaced by one of relative permittivity 2, the capacitance of the cable will become Double Four times One half None of the listed here Double Four times One half None of the listed here ANSWER DOWNLOAD EXAMIANS APP
Electrical Cables Solid type cables are considered unreliable beyond 66 kV because Insulation may melt due to higher temperature Of corona loss between conductor and sheath material Skin effect dominates on the conductor There is a danger of breakdown of insulation due to the presence of voids Insulation may melt due to higher temperature Of corona loss between conductor and sheath material Skin effect dominates on the conductor There is a danger of breakdown of insulation due to the presence of voids ANSWER DOWNLOAD EXAMIANS APP
