Honors Physics Chapter 11 Part 3

a flow of electric charge. This charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

• electrical power

• work

• resistivity

• electrical current

the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

• electrical power

• work

• resistivity

• electrical current

a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current.

• electrical power

• work

• resistivity

• electrical current

a force that when acting, causes a displacement of the point of application in the direction of the force

• electrical power

• work

• resistivity

• electrical current

the potential drop (V-voltage), current flow (I-current), resistance (R) and power dissipated (P-power) for each element in your circuit, as well as for the circuit as a whole.

• equivalent resistance

• Kirchhoff's current law

• Ohm's law

• VIRP table

states that the algebraic sum of ALL the currents entering and leaving a junction must be equal to zero as: Σ IIN = Σ IOUT.

• equivalent resistance

• Kirchhoff's current law

• Ohm's law

• VIRP table

a law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. V = IR

• equivalent resistance

• Kirchhoff's current law

• Ohm's law

• VIRP table

the resistance of two parallel resistors is defined by: 1 / R e = ∑ 1 / R i. For two series resistors, it's simply the sum of the individual resistances of each resistor.
