Batteries

Power

Kirchhoff's Rules

Electromotive Force text

Explain the concept of electromotive force.
Explain the concept of terminal voltage.
To maximize the percentage of power from the emf of a battery that is delivered to a device external to the battery, what should the internal resistance of the battery be?

Resistors in Series text

What is the relationship between the current across several resistors in series and the individual resistances of each resistor?
What is the relationship between the voltage across several resistors in series and the individual resistances of each resistor?
What is the relationship between the power developed by several resistors in series and the individual resistances of each resistor?

Resistors in Parallel text

What is the relationship between the current across several resistors in parallel and the individual resistances of each resistor?
What is the relationship between the voltage across several resistors in parallel and the individual resistances of each resistor?
What is the relationship between the power developed by several resistors in parallel and the individual resistances of each resistor?

Kirchhoff's Rules text

What is Kirchhoff's Loop Rule and how does it reinforce the relationships you identified above?
What is Kirchhoff's Junction Rule and how does it reinforce the relationships you identified above?
Two bulbs with different resistances are connected in series to a battery, with the resistance of bulb 1 greater than the resistance of bulb 2. They are then disconnected and reconnected to be in parallel. Describe their relative currents, voltage drops, and power outputs in each circuit.
How does a branch with zero resistance affect other parallel branches?
