Question

1. a simple circuit consists of a conductor, wires, and __ battery
2. as energy carried by a current increases, __
3. electric energy can be stored by __ charges.
4. in a battery, electrons flow from the negative terminal to the positiv terminal.
5. when a wire is made thicker, its resistance decreases
6. the unit used to measure electric current is the ampere
7. according to ohms law, voltage = current x resistance

Explanation:

1. The power (P = VI) is related to energy carried by current. As energy - carrying current increases, power increases.
2. Capacitors store electric energy in the form of an electric field between their plates which is related to charges.
3. In a battery, electrons flow from the negative terminal (where they are in excess) to the positive terminal.
4. Resistance (R) is inversely proportional to the cross - sectional area (A) of a wire (R = ρL/A), so when a wire is made thicker (A increases), resistance decreases.
5. The SI unit of electric current is the ampere.
6. Ohm's law is expressed as V = IR, where V is voltage, I is current, and R is resistance.

Answer:

1. Power
2. Capacitors
3. Negative; Positive
4. Decreases
5. Ampere
6. Current; Resistance
