Worksheet time: 10mins
Batteries convert
chemical to electrical energy
electrical to chemical energy
chemical to kinetic energy
electrical to potential energy
A cathode of a battery is
the positive electrode
the negative electrode
the neutral electrode
zinc
The anode of a battery is
the positive electrode
the negative electrode
the neutral electrode
the copper
The electrolyte of a battery
supplies electrons for the battery
allows chemical reactions to occur
contains electrical energy
is only a liquid
A circuit
is a continuous path for electron flow
is a broken path for electron flow
must have a swtich
must have at least one component (like a light bulb)
Current is
the amount of energy an individual electron has
the number of electrons stored in a battery
a measure of how many charges pass a point per unit time
the number of volts in a circuit
Current is measured with
a voltmeter
an ammeter
a resistor
a meter stick
An ammeter in a circuit may show the following units:
amperes (A)
milliamperes (mA)
volts (V)
millivolts (mV)
Voltage is
the amount of energy each charge in a circuit has
the number of charges flowing through a point per unit time
electricity
measured with an ammeter
Electrons flow from
anode to cathode
negative to positive
cathode to anode
copper to zinc
Conventional current flow
is opposite that of electron flow
is the same as electron flow
travels through insulators
cannot be determined
The LED
is off because the switch is open
is on because the LED is closed
is placed in the circuit backwards
requires more voltage to turn on
How many batteries are in the circuit?

State the correct aspects of the schematic drawing
The corners are squared
Standard symbols are used
The corners are curved
The lines of the conducting wires are not straight
The circuit on top is wired
in series
in parallel
with a single battery
with four batteries
The circuit on the bottom is wired
in series
in parallel
with a single battery
with four batteries
The circuit on the bottom has
one path for charge flow
two paths for charge flow
three paths for charge flow
one battery
The voltage readings shown here
differ because the voltage drops are shared across components
are the same because the voltage is the same everywhere in a series circuit
The current readings shown here
differ because the current splits in a series circuit
are the same because the current is the same everywhere in a series circuit
The current readings shown here
differ because the current splits in a parallel circuit
are the same because the current is the same everywhere in a parallel circuit
