1. How is electric power typically measured?

a. In volts (V).     b. In ohms (Ω).       c. In amperes (A).       d. In watts (W).

2. What happens to the power dissipated by a device if both the current and voltage across it are doubled?

a. The power is halved.   b. The power is quadrupled.  c. The power is doubled.   d. The power remains the same.

3. In an electrical circuit, how does the power consumption of a device change when the resistance is decreased while keeping the voltage constant?

a. Power decreases.      b. Power increases.     c. Power remains the same.     d. Power becomes zero.

The electric power P "consumed" by an electrical device is the product between the voltage V at the terminals (in Volts) and current I passing through it (in amps): P = V × I The unit of power is the Watt (W).

Benefits of Bubbl.us mind maps over text:

Superior clarity of structured information

Whether it's a family tree, a decision flow map, or an algorithm, mind maps have a huge advantage in presenting complexity clearly and concisely.

Better retention of complex ideas.

Visualizing complex ideas in shapes, lines, and pictures leads to much better recollection later than simple text.

Creative collaboration with others.

Visual brainstorming with a team can dramatically improve the quality of the final product because of diversity of perspectives and experiences.
