Study Guide for 2.3 to 2.6 Assessment:
Section 2.3: Batteries
Vocabulary- battery, wet cell, dry cell, electrode, electrolyte
Concepts:
 Volta created the first battery by layering zinc with silver and paper soaked in salt water
 Luigi Galvani discovered “animal electricity” with his for leg experiment
 Label the parts of a wet cell (see notes)
Section 2.4: Electric Circuits
Vocabulary- electric circuit, Ohm’s Law, series circuit, parallel circuit
Concepts:
 Ohm’s Law is calculated by the following equation:
o Resistance Ω= Voltage (V)/ Current (A)
 Symbols and Features of a circuit:
o Resistors
o Voltage Source
o Conducting Wires
o Switch
 Label a series and parallel circuit
Section 2.5: Power
Vocabulary- power
Concepts:
 Power is calculated by the equation:
o Power (watts)= voltage (V) x current (A)
Section 2.6: Electrical Safety
Vocabulary- Circuit breaker, Fuse
Concepts:
 Short circuit is a connection that allows current to take the path of least resistance
 In order to prevent circuits from overheating, devices called fuses and circuit breakers are added to circuits

