We have two Kirchhoff's laws:

Kirchhoff's junction rule and Kirchhoff's loop rule

Kirchhoff's loop rule relates the voltages in a loop.

1. How many laws are named after Kirchhoff?

2. Which has a larger resistance, a 60 W lightbulb or a 100 W lightbulb?

3. What property of a real battery makes its potential difference slightly different than that of an ideal battery?

4. In an RC circuit, what quantity is represented by the symbol τ?

5. The junction rule describes the conservation of which quantity? Note that this rule applies only to circuits that are in a steady state
