They are generally used in polyphase systems, with high currents, or when protection from environmental hazards is required.

This high current can destroy components, melt insulation, and start a fire.

The electron transfer reaction is very fast, and can be accompanied with high currents.

To extend the range to higher currents, a current divider may be used.

All of these gave excessive forward voltage drop at high currents.

The site offers both high currents and shelter from storms.

Then the boat was gone, out into the high, swift current of the river.

This makes fast recharging possible and provides high currents when needed.

A very high electric current is passed through the joint and fuses the two pieces of metal together.

Depending on the gun design, fine focus or high current can be obtained.
