Is a bulb a conductor or insulator?
Electric bulb is basically an insulating device. By calling it an insulating device it does not mean that it completely disallows the flow of electricity! It means that the device or object resists the flow of electricity to some extent. It has a coil of a metal called Tungsten which resists the flow of electricity. Due to this resistance the coil heats up immensely and glows hot. However, this coil of Tungsten does allow some electricity to pass through so that the circuit of electrical flow remains closed/complete and the electric bulb remains lighted.
What device creates a potential difference in an electric circuit?
resistor
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
Will a copper penny complete an electricity circuit?
Yes. Copper is a very good conductor. But a penny is not a safe device to include in an electrical circuit.
Describe how an insulator can slow a transfer of energy?
Insulators can slow the energy transferred because since insulators make electric current pass slowly because of the insulator is a device to slow down the current
What is a rccb?
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.

When is a switch an insulator?
A switch is a device that can either be a conductor or an insulator. When the switch is off, it becomes an insulator and resists the flow of electricity.
Is a lamp contact a conductor or insulator?
The "contact" ... that is, the point where one side of the power circuit is connected ... must be a conductor. When the switch is 'open', then one contact is physically separated from the other one, and no current flows between them. But the contacts themselves are still conductors.
Is wood an insulator?
Wood is a gd insulator as it is a poor conductor. whereas metal is a gd conductor but poor insulator.
What is a device used to open and close an electric circuit?
The device is called a switch.

What is the function of a combination pliers in an electric circuit?
for made of electric circuit safety device,
What is the function of electric circuit control device?
the function of the control device is that you can know if the circuit is on or off
What is the function of the voltmeter in an electric circuit?
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
