From Green Ronin’s webstore:

Each Power Profile takes a look at a particular type of super-power in Mutants & Masterminds game terms, putting together the effects and modifiers from the Hero's Handbook to present different abilities associated with that power, from offensive and defensive to movement and utility. It also discusses different power descriptors and how they affect game play, as well as features and complications associated with the power. It's a ready-made guide to creating new heroes and villains for your M&M game!

Power Profile: Electrical Powers

From the thunderbolts of the gods to the energy sustaining the modern world, electricity is a power to reckon with, and Electrical Powers range from hurling bolts of lightning or stunning taser blasts to absorbing and conducting the output of a city's power-grid, or "riding the lightning" by transforming into electricity and traveling in the blink of an eye.
