It is a battery that is made up of a dry acid paste enclosed by metal plates with a carbon rod at its center.
dry cell
wet cell
power plant
It is a battery that contains metal plates or rods that are dipped in liquid chemical.
dry cell

Voltage is a pushing force that is present in a battery and causes electricity to flow from the battery into an electronic device.
TRUE
FALSE
It is the third component of the electric circuit. It is the device that converts electrical energy into another form of energy.
energy source
wire
load
switch
It is the fourth component of a circuit. It controls the flow of electricity. It is an electrical device that allows you to open or close a circuit.
energy source
wire
load
switch
It is the first component of an electric circuit which is commonly a battery or a generator.
energy source
wire
load
switch
These are materials that allow electricity to pass through them and flow easily.
conductors
insulators
These are materials that do not allow electricity to pass through them.
conductors
insulators
It is the entire system by which electricity flows within a device.
circuit
current
electricity
It is a circuit that allows electric current to pass through several paths. In this circuit, the bulb is connected separately to the ends of the dry cell.
series circuit
parallel circuit
It is a circuit that has only one path through which electric current passes. In this circuit, electricity passes through a set of loads connected in series or in a straight line.
series circuit
parallel circuit
It occurs when two wires that should not have contact with each other actually do so, usually because their insulation has worn out.
short circuit
power surge
It is a condition in which there is too much current in the circuit.
short circuit
power surge
It is consists of metallic ribbon enclosed by an insulated housing. When there is too much current, the ribbon will melt and opensthe circuit.
circuit breaker
fuse
When an electric current travels through conductors in a complete circuit, the circuit is called __________.
closed circuit
open circuit
If the switch is open, but the continuous path of electricity is blocked by an insulator such as air, then the current stops to flow. This is called an ____________.
closed circuit
open circuit
It is the second component of an electric circuit.
energy source
wire
load
switch
