Why is High Voltage called High Tension?

Voltage is considered as electrical pressure as it exerts pressure or tension on the dielectric or any insulators to form electric dipole and tries to penetrate it. Hence a high voltage overhead transmission line exerts a high “electrical” tension(penetration force) on the insulator discs.

Is 60v dc dangerous?

A voltage of 60V per cm across your body will cause tissue damage. If the entry and exit points are somewhere like your leg, you can survive even the frighteningly high voltages from lightning. If the voltage goes across your heart, even 100VDC could be fatal and stop it.

Can DC current kill you?

DC can shock you as well. It's just that more current is required in case of DC to feel the shock than that required for ac. This is due to the fact that the current flowing through our body depends on four factors. Above 25-30mA, the current flow through our body is dangerous.

Can a hybrid battery kill you?

When every second counts, a hybrid car could be your worst enemy. Cummings says the issue stems from the high voltage cables running through the car's frame, which are connected to the battery. "Most of the amperage in the hybrids can be upwards of 100 amps or greater, so the potential to kill you is right there."
